Testimonials
What our patients are saying
"My 4-year-old had a cough for 4 months. Her pediatrician said just wait. The same thing happened last year in the same season. The doctor, Dr. Avshalomov, was attentive with testing and medication recommended. One week later, she is feeling much better."

"I have previously posted on Facebook about how Dr. Gadi is such an incredible Doctor of Allergy and Immunology who has saved my life (never gets too old or boring). I joke with him that I believe he is 1 of 36 righteous men (or women) put here to take care of all of the children, women and men requiring special care. He never stops smiling or caring. He will always sit with me and answer all of my health-related questions, no matter how many times I may have previously asked that same question."

"Dr Gadi has been treating my son for over 5 years. He was born with RSV and asthma from day one. I almost lost him day 5 he was turning blue. My son was hospitalized over 20 times and at least 40 ER visits over the course of 11 years for asthma issues. I put the allergist off as long as I could but my pulmonologist kept pushing me. At one point my son had lung disease I can't tell you how helpless he was, one time he collapsed on the floor in the ER... Dr Gadi is a true doctor, I didn't believe him at first, but I am a true believer he has saved my son's life. He has not had an asthma attack within the last 5 years. Thank you Dr Gadi from the bottom of my heart for all that you have done for my son."

"Dr. Gadi is a very efficient doctor. I've been seeing him for years for allergy shots and have always found him attentive and quite polite. He's very professional and has minimal waiting times for appointments. His staff is also quite polite and professional, particularly the nurses who administer allergy injections."

"My son went to Dr. Avshalomov after constantly being sick. He was diagnosed and treated and has not been sick since Dr Gadi treated him almost seven years ago and I've spoken to other patients with a similar outcome. He explains things so you understand the full situation."

"I took my daughter to see Dr. Gadi as she was referred by her pediatrician. I was skeptical after reading some of the reviews however it was a great appointment. Dr. Gadi was very warm and patient with my daughter. He spent a lot of time with us and was very informative. It was a great appointment overall also Sophia at the front desk was really reassuring after I called prior to appointment with my concerns."
