Elevate Your Mind and Body through Ketamine Therapy, TMS Therapy and Vitamin Infusions in Orange County, CA

Deciding to get ketamine treatment is the best decision I’ve ever made for my well-being. Dr. Seif has created the perfect atmosphere for patients to feel safe and at peace during treatments. Her and her staff always made me feel safe and welcome, guiding me through every step of the process which eased my anxieties. It felt like a personalized treatment, and I looked forward to going each time. I would highly recommend this treatment and Dr. Seif’s center for anyone who is looking for long-term relief from various mental and physical health issues.

Upon entering OC Ketamine Therapy, you’re immediately met with a sense of calm and relaxation, thanks to the soothing aesthetic and tranquil atmosphere of the office. Dr. Seif and her team make you feel right at home. The ExoMind machine is located in a separate, serene room, complete with a comfortable recliner and cozy blanket. During the session, the ExoMind delivers gentle pulses to the scalp while you relax. It’s effective for treating ADHD, OCD, depression, anxiety, and insomnia. I felt immediately relaxed after my session and look forward to completing the full series. The doctor and staff are incredibly warm and caring, making the office feel like a true safe haven. Highly recommend!

I can’t say enough good things about Dr. Seif! From the very first visit, she made me feel completely comfortable and genuinely cared for. Dealing with a lot of anxiety and cognitive issues post partum I decided to try ExoMind treatments. She took the time to listen, explain everything about the ExoMind treatment, and answer every question with patience and kindness. The treatment itself has made such a positive difference. You can tell she truly wants the best for her patients and goes above and beyond to make sure you’re supported every step of the way. I’m so grateful I found her and highly recommend Dr. Seif to anyone dealing with post partum issues. It’s been a game changer. Thank you Dr. Seif!

I had the opportunity to work with Dr. Seif at OC Ketamine Therapy, and I genuinely can’t thank her enough. I came in after being laid off from my job, feeling emotionally flat, anxious, and stuck in a semi-depressive state. My energy was almost nonexistent, and I had become very internal—keeping my thoughts and feelings bottled up, barely engaging with those around me. Dr. Seif introduced me to her ExoMind protocol, and the effects were immediate—far beyond what I expected. After just one session, I didn’t consciously feel different at first, but my family quickly began pointing out how my behavior had shifted. I went from isolating myself to planning outings, being more talkative, and just overall more present. Right after that first appointment, I realized I wasn’t letting the little stresses of daily life get to me. I felt lighter, calmer, and much more open—something I hadn’t experienced in a long time. The anxiety that used to sit on my chest all day started to loosen its grip. Dr. Seif was incredibly professional and kind throughout the process. She took her time to explain everything clearly and made sure I felt supported at every step. Her calm presence and deep knowledge made a world of difference. If you’re feeling stuck, low-energy, or overwhelmed by anxiety like I was, I can’t recommend Dr. Seif and ExoMind enough. This experience has genuinely been life-changing.

I had such a positive experience at OC Therapy. The environment is calm and welcoming, and the staff makes you feel cared for from the moment you arrive. Dr. Seif is an exceptional physician—she listens closely, explains everything with clarity, and approaches care with a rare combination of expertise and compassion. Her warmth and professionalism immediately put me at ease, and I left feeling truly supported. I would highly recommend OC Therapy to anyone seeking attentive, thoughtful, and high-quality care. Dr. Seif’s dedication to her patients is evident in every interaction.

Ketamine IV Infusions changed my life for the better - OC Ketamine Therapy is the best there is. Dr. Seif is absolutely lovely! Her professionalism, compassion and knowledge around Ketamine, in addition to the comforting, calming environment, fosters a setting of self-discovery and intrinsic growth. I'm someone with a lack of trust in medical providers, so going to any new practice is anxiety-provoking. Dr. Seif and the team at OCK Therapy was understanding of this and made me feel right at home. If you think that Ketamine therapy is the path for you, I highly* recommend OCK Therapy and Dr. Seif.

I’ve had other ketamine experiences, but this is different. OC Ketamine Therapy and Dr. Seif offer a level of care, presence, and personalization that’s truly rare. Each session is tailored to what I need in that moment, and it’s become a powerful tool in my mental health tool belt. It’s not just about symptom relief—it’s about real healing. As a working mom in the healthcare space, I’ve found this to be an invaluable investment in my well-being.

Dr. Dina was amazing. She was thoughtful and kind and her office was so calming. I tried the exomind and ketamine therapy together. Wow!!! Definitely helped.

I tried ketamine therapy for the first time with Dr. Seif, and am very grateful that my friend recommended me to her. I felt very comfortable at the clinic and the atmosphere is very calming. I really appreciated the guidance and insight I received at OC Ketamine and have returned for more sessions, and plan on going back. I highly recommend working with Dr. Seif and OC Ketamine.

Such a wonderful experience. A super warm and inviting environment. The Apollo band helped make my infusion so much more comfortable, truly impressed.

Amazing office!Amazing experience!Dr. Seif and her staff are FANTASTIC!If you're looking for ketamine therapy or Exomind therapy, look no further.

Dr. Seif is not only an excellent physician but also a genuinely kind and compassionate person.Alexa is wonderful—always friendly, helpful, and quick to respond.

Dr Seif is a compassionate doctor who is bringing very-needed wellness treatments to the OC. Her clinic is a beautiful facility that evokes calmness and peace.

I’m very grateful to have found Dr. Seif. I suffer from Anxiety, Depression and OCD. With past addiction issues. This medicine truly works! I’m hopeful it will help me make the changes I need in myself to do great things in the near future. I can’t express how happy I am to have met Dr. Seif and Alexa at the front desk. Both exceeding my expectations for what great work they do. I loved every bit of my time with them. I’ll be coming back to them for my future care! Thank you both!

Some of the most important parts of a ketamine therapy experience for me are feeling safe and being in a supportive environment. Dr. Seif and her staff exceeded any expectation I had of what that experience could be. OC Ketamine Therapy is the perfect balance between medical grade safety and spiritual care. Thank you Dr. Seif for sharing your expertise and art with me.

OC Ketamine Therapy was nothing short of divine intervention for me. They talk about the importance of set and setting in psychedelics, so I was careful to find a clinic and provider that felt like a good match. Dr. Seif is a warm, genuine person who brings a positive, authentic, empathetic and healing presence to the experience. I highly recommend this clinic.

I am deeply grateful for the transformative experience I’ve had with Dr. Dina Seif and the team at OC Ketamine Therapy. Before coming to Dr. Seif, I had been using Ketamine troches at home since May in an attempt to find relief from my Major Depression Disorder, PTSD, trauma, and anxiety. Unfortunately, they weren't providing the breakthrough I so desperately needed. That all changed once I began working with Dr. Seif. The in-office Ketamine sessions with Dr. Seif provided the deep healing I had been searching for. Not only did they help me address my mental health challenges, but they also sparked a profound spiritual journey that has shifted my entire outlook on life. I now feel like a blank canvas, ready to paint a new mural for the next chapter of my life. Where my heart once felt empty, I now feel whole again. There’s a newfound sense of peace, clarity, and hope—emotions I had long forgotten were possible. Throughout my sessions, three words stood out as guiding lights: Compassion, Love, and Happiness. These words not only defined my therapy sessions but also encapsulated the approach Dr. Seif and her team take with every patient. Dr. Seif’s compassion is evident in every interaction. She truly listens, and her care made me feel seen, understood, and supported. I felt a deep sense of love and kindness, and, for the first time in what felt like forever, I started to experience real happiness again. I also want to take a moment to mention Alexa, who greeted me at the front desk with warmth and kindness each time I arrived. She made me feel at ease from the moment I walked in. The office itself is beautiful, with an ambiance that instantly made me feel safe and cared for. It’s a calming space that felt conducive to healing—exactly what I needed as I began my journey to recovery. I am incredibly thankful to Dr. Seif and the entire team at OC Ketamine Therapy for their exceptional care and for guiding me through this life-changing experience. I feel like I have been given a second chance at life, and I’m filled with hope and excitement for the future. If you’re struggling, I highly recommend this treatment—it’s been a gift that has changed my life for the better.

Dr. Seif is excellent. Alexa, her coordinator is excellent. The space that they have created, and hold is excellent. Five years ago I underwent treatment in a very similar space, with people who cared just as much. I received nine treatments in a month’s time, and it completely relieved my crippling anxiety, ptsd, and depression. With several follow-up sessions, over a year, I was able to discontinue all medications. I made the mistake of not continuing with “maintenance” sessions for more than a year, as I believed that I was in permanent remission. Eventually, I fell back in to my previous pattern of depression, anxiety, and panic. Eventually, I returned to taking the same meds that I had for years. I wish I would have never stopped kat. I did try to restart treatment in spaces that felt unsafe. They likely had a negative impact on my wellbeing. The medicine of ketamine is vital. It’s safe and productive. The difference, in my experience, is the setting, and practitioners. Dr. Seif and Alexa are safe, and respond to your every word. 😉 I know that they’re going to bring me back to life.

There are not sufficient enough words to describe what ketamine and Dr. Seif has done for my life. First of all, Dr. Seif is exactly who you want to have you guide you through this very vulnerable and at times emotional state. My parents quoted: "after meeting with her, I would put your life and mine in her hands." I have come to love her dearly. Ketamine is like nothing else. It has erased all fear of death from my life, and as a person living with a brain tumor, this is no small feat. Most importantly, as an addict, after completing 6 rounds plus a booster of ketamine, I was able to quit an extremely addictive street opiate that i was addicted to for 4 years. I've quit lots of vices before but NOTHING worked on this drug. But i quit it after ketamine. I'm talking cold turkey. The ketamine will show you what you need to work on (at least in my experience) and then give you the motivation to see your goal through. Every addict should have this tool at their disposal. There are still rough days! But since the ketamine I am able to cope with more emotional stress without turning to a drink or drug. And the hard days just aren't AS hard and they are few and far between. I feel incredibly lucky to have had this experience, and most importantly to have worked with (and continue working with) an angel like Dr. Seif!

Dr. Seif is a caring and intelligent doctor with an intuitive nature that can’t be taught. She cares about the whole experience and puts emphasis on more than just administering medicine, paying special attention to the other details like set and setting and individualized care. On one hand, you feel like you’re at a Drs office, in the sense that your health and safety are taken care of. On the other hand, you feel like you’re at a wellness spa/retreat, because the environment is so comfortable and calming. Beyond the great things I have to say about this business, the IV ketamine treatment itself is an incredible option that can offer hope where there was none, or even just open space for growth and healing. This can be such an incredible option for such a wide variety of human beings.

Dr. Dina Seif has made this experience exceptionally calming. After spending six months researching various doctors from Beverly Hills to Newport, I found that Dr. Dina’s office stands out as one of the best. The office atmosphere, along with the staff, exudes a sense of calm and safety. Unlike a typical doctor’s office, Dr. Dina’s office has a spa-like energy. Everything is of the highest quality, from the weighted blankets to the comfortable chairs. This experience requires a calm and warm environment to work its magic, and Dr. Dina’s office provides just that.

Dr. Seif is beyond amazing. These treatments made the most positive impact in my life and I am so grateful for the amazing experience!!

Dr. Dina Seif is fantastic! I had my first ketamine session last April. I have been on antidepressants for over 15 years , but I was not at peace nor could I feel joy for more than a few minutes at a time. I knew that there was more to life than just maintenance. When heard about all the successful treatments for depression with Ketamine I knew that I wanted to try it. After my first treatment I could actually feel the cloud of depression start to dissipate. By my 6th treatment I began to live my life from my heart. I took my grandchildren for vacation, went to my high school reunion. Fell in love, learned how to speak my truth, lost 20 pounds, got my heart broken. Took dance lessons went to a bunch if concerts. Then I got in touch with my high school sweetheart. I fell in love all over again. I no longer have to talk myself into leaving my home for errands or leisure. I just go and do it. I have stopped thinking about life and began to live my life. I've had three follow-up treatments with Dr. Seif and each time I set my intentions to allow myself to love. I intend to let others love me and I allow myself to love others and spend quality time with each of my loved ones. Life is truly joyous for me. At age 68, I am living my best life, loving every minute. I am so thankful for OC Ketamine Therapy and eternally grateful to Dr Seif.

Suffering from depression for so many years and not seeing the light at the end of the tunnel made me search for something completely different. After doing some research I decided to try a different approach any give it a try with Ketamine therapy. That was the best decision I could have made in my life as Rx never really worked for me. So my journey started when I found Dr. Seif with OC Ketamine and feeling a difference right after the first Ketamine therapy session . Dr. Seif made me feel safe and comfortable from the beginning as she is very professional and caring.

Dr. Seif was incredibly kind, compassionate, and capable. She took the time to answer all of our questions (in person and between appointments) and provided excellent care. Her space was warm and welcoming. Fantastic experience for my daughter- this was one of the first therapies that has been impactful for her. I would highly recommend working with Dr. Seif.

I can’t say enough good about the therapy and the doctor. Dr. Seif is awesome. From the first time I contacted her office she picked up the phone and we talked a little bit. Just from that first conversation I knew that I was going to be in good hands. She does every thing and is always involved in the therapy. We had great talks before and after the therapy. She is like a psychologist with excellent insights and understandings. She truly cares and wants better for her patients. The therapy was the best experience I’ve had to treat my depression and grief. I tried several antidepressants and none gave me relief. But with the ketamine I made incredible progress towards feeling better. From the first treatment I felt weight lifted off my psyche and built on the positive thoughts and feelings in other sessions. If you are even just thinking about doing ketamine therapy give Dr. Seif a call. I’m sure once you talk with her you will know that going with Dr. Seif is the right thing to move forward with this treatment.

Dr. Seif and the staff were amazing and genuine. Dr. Seif spent lots of time with her patients. She is passionate and cares a lot about her patients from all aspects. She attends the sessions and monitor the patient well. I would strongly recommend her without hesitation. We are very thankful to her and the staff.

Having received ketamine infusion treatments from Dr. Dina, my life has changed for the better. Prior to that, I felt like all I did was struggle to survive, even with all of the therapies, treatments, and medications I've taken. Choosing ketamine was a very discerning process, but it seemed safer than some (or all) of the prior meds I've taken. Turns out, ketamine was the best intervention for me for my CPTSD. Even from the first treatment, I finally felt... normal! I felt like I can finally start living life without the feeling of hypervigilance that comes with CPTSD. Since my first ketamine infusion session with Dr. Dina, I am able to do the work to move forward with my personal development, as well as advance my career. It's been almost 3 years and I've come a long way. I finally have a healthier with myself and also my loved ones. I still have some more development to do, but I'm glad I'm able to actually it! Grateful for Dr. Dina and ketamine infusion treatments!

Dr. Dina Seif started treating my teenage son for intractable depression in the summer of 2021. Dr. Seif is a true expert in field of Ketamine therapies which is the utmost importance when considering this treatment modality. She is professional, compassionate and understanding. My son is doing very well and we are so grateful to have found Dr Seif and recommend her highly.

My 14yr old daughter has struggled with treatment resistant depression for 2 years, despite being on several medications, at 2 different IOPs, a 7 week residential program and countless hours of individual therapy. She has also made 5 suicide attempts over the past 2 years. She started Ketamine IV’s with Dr Seif in late May 2023. We feel this has been the best decision we’ve made for our daughter’s health and life. She responded very well to the first 6 treatments and this morning she had her first “booster”. Dr Seif is an amazing woman and doctor. From the very first phone call we knew she was special. She took time with us (and our daughter), answered all of our questions and genuinely seemed to care about our daughter and her challenges. Dr Seif spoke to our daughter like she was a person and included her in all conversations making sure our daughter understood what was happening and that she was comfortable with the process. Our daughter started at a new residential treatment center (Compass Behavioral Health) at the same time as her Ketamine treatments. The residential program focuses on DBT skills. Learning DBT along with the Ketamine has changed our daughter from wanting to take her life to having a Life Worth Living. We will forever be grateful to Dr Seif for all she has done for us.

Our 17 year old son has struggled with depression, anxiety, disordered eating and suicidal ideation for some time, and it became quite serious August 2022. He had been admitted to a residential treatment program in the area in May 2023 after spending time in intensive outpatient therapy, 2 PHP programs, 2 residential programs, and an inpatient program over the past 10 months. He had multiple suicide attempts and self harm in and out of these programs. He started Ketamine IV’s with Dr. Seif in June 2023. She explained everything to Dad and me and then met with our son individually so he could discuss questions that he had. We feel that these treatments made a significant difference in our son’s treatment. He had the first 6 treatments, as well as two follow up treatments. Dr. Seif took time with our son before, during and after each treatment and was always there to answer any questions. We were very comfortable through the entire process. When my son returned home, we live in CO, after discharge from the residential program he had been in, she helped us with finding a provider at home that would be a good fit for our son for any follow up treatments he might need. Dr. Seif continues to inquire about our son and has ensured the new clinic has all the information needed to make the transition as easy as possible. We value everything that she has done for our son and the care that she continues to show for him.
