Welcome!

Welcome to Foothill Pediatric and Adolescent Clinic! For almost 50 years, our experienced and caring pediatricians have provided world-class care for families throughout the Greater San Gabriel Valley. If you’re looking for accessible pediatric care, a child-friendly environment, and a responsive team of pediatricians centrally located in the San Gabriel Valley, then look no further. We love our patients, and our goal is to have a positive impact in the lives of children by providing exceptional healthcare and compassionate service to the families we serve.

At Foothill Pediatric and Adolescent Clinic, we offer comprehensive pediatric care including prenatal visits for expecting parents, in-hospital care, developmental evaluations, well-child check-ups, immunizations and sick appointments. We also perform specialty services including newborn circumcisions and ear piercings. We are one of the few clinics in the region that offers same-day appointments and 24 hour access to your doctor. Our caring team is committed to providing quality service in a comfortable, safe office setting where children and parents can feel at ease. We also set aside time to equip parents with the tools and resources necessary for the development of healthy children from birth through adolescence.

We invite you to take a few moments to browse our website and familiarize yourself with our clinic. You will find all the information you need, including doctor bios, service details, directions to our clinics, and new patient forms. For questions or to schedule a visit, please contact our office today! We are here to serve you.

Clinic Overview

Our clinic was founded by George M. Madanat, M.D. in February of 1975. Now serving our patients are Michael G. Madanat, M.D., Lana Madanat Hadaya, CPNP. , Bernardine Celoni M.D., and Irma Gonzalez, M.D., April Gacuya, CPNP, Sarah Wong, PA, and Rebecca Byer, CPNP.  Our clinicians have helped tens of thousands of families reach optimal health and wellness, and despite the growth of our business and adoption of modern technologies, we continue to offer the same classic, family-oriented appeal and patient first culture that so many clinics have lost.
