What Others Say About Us

I am a general pediatrician with a special interest in ADHD, spending about 20% of my clinical time caring for ADHD patients. I have known Dr Pontillo since 2005 and have an enormous respect for her clinical skills and insights. She is my “go to” psychologist for more complicated developmental issues and for diagnosis of subtle high functioning disabilities. Dr. Pontillo’s interest in her patients and her ability to clearly delineate developmental problems allows parents to move forward with establishing a treatment plan. She is an invaluable resource to the San Diego Pediatric community.

Nicholas Levy, MD, Medical Director, El Camino Pediatrics, V. Asst Clinical Professor, School of Medicine, UCSD

Dr. Pontillo is an exceptional, and one-of-a-kind child psychologist. I have referred many children of my patients to Dr. Pontillo and she has always given them the best care and attention. Referring a patient to another professional is a big responsibility. I always look for a colleague who is efficient, professional, experienced and one who is able to come up with a clear diagnosis. I keep referring to Dr. Pontillo because of her expertise, efficiency and especially her warm and caring personality that is extremely necessary when dealing with children. I very highly recommend Deborah Pontillo, Ph.D as a child diagnostician, developmental and behavioral specialist, and therapist.

David Kravetz, M.D., Professor of Clinical Medicine, School of Medicine, UCSD

I’ve been referring my patients to Dr. Pontillo for the past several years with the utmost confidence that she will care and understand their developmental needs. Dr. Pontillo always provided them with a balanced and age appropriate intervention to help not only the child but the family as a whole.
