Starting March 24th 2021, we will be offering monoclonal antibody therapy for patients suffering from active COVID-19 infections.
In order to keep the offices sterile from Covid these infusions will be carried out in a drive-through manner, in the patients' vehicles accompanied by at least one family member. There will be no charge for medication as we are working in conjunction with New York State in an attempt to improve the well-being of our communities. Patients will have to register with the practice and may be responsible for a visit co-pay/deductible only.
Monoclonal antibody therapy will be given to patients with symptomatic COVID-19 infections and it has been shown to dramatically reduce hospitalizations and mortality from COVID-19. Please be patient with our staff and facilities while we incorporate new protocols which enhance the safety, well-being and delivery of care to all the members of our community.
Thank you

  • Thank you Dr Gadi from the bottom of my heart
    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 y son had lung disease I cant tell you how helpless he was, one time he collapsed on the floor in the ER ... Dr Gadi is a true doctor, I didnt believe him at first, but I am a true believer he has saved my sons 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. Best Theresa McCormick

  • Always found him attentive and quite polite
    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.

  • He explains things so you understand the full situation.
    My son went to dr Avsholomov 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 give a solid 5 stars

  • I took my daughter to see Dr. Gadi
    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.

  • Many years I suffered itchy rashes on legs , arms and hands
    Many years I suffered itchy rashes on legs , arms and hands ..
    I went to numerous dermatologist whom only gave me ointments and creams but the rash never was cured ...
    I'd just about had it with the rash & the ointments and creams not working....

    After years of being sent to dermatologist and nothing helping me, my PCP. Dr referred me to an allergist...
    I thought I'd give it a try...What did I have to lose ? , Except for the rash and itch ..

    I started attending this office by seeing the Dr first and then patches and breathing test etc.
    I for one feel that when starting a new Dr. Office it's very helpful to the patient's ( me) when the staff is down to earth and kind ... They make you feel welcome and at ease ...

    In the four months I've been going to Dr Gadi and having weekly immunology shots I've noticed a great difference with my itch and my rash blotches have disappeared from my legs, arms. And hands ....I'm extremely pleased...

    I've certainly recommended this Dr office to many people...
    I've given out their office cards to people who are in need of an allergist....
    When they ask :" Is he good? How's the office staff?

    My answer: " Yes he's a good Dr. And his staff are down to earth and always greeting their patients with kindness ...
    I have only nice things to say about Dr Avshalomov office ...

  • I absolutely adore Dr Gadi!
    I absolutely adore Dr Gadi! He helped diagnose my daughter and advised me on how to handle her treatment. Never felt rushed and he always made sure I understood everything. He is a very kind and honest man and looks you in
    the eye when speaking to you. I would highly recommend Dr. Gadi for any immunology problems you may have.

  • I highly recommend Dr. Gadi!
    There are few Dr.'s nowadays that truly care...and you can feel that sincerity, and genuity from the second you meet Dr. Gadi. In my experience the element of caring has been removed from our health care system. Dr. Gadi is so patient with his patients (excuse the pun) taking the time to "talk" to you and really make you feel that when you are in his treatment room you, and the issue you've come to see him for, is the only thing on his mind. I highly recommend Dr. Gadi!

  • He comes highly regarded by me
    We have been going to Dr. Gadi's office for years. Our daughter had suffered from pneumonia 5 times in her first three years of life and my wife and I were beside ourselves. Multiple opinions were that our daughter had cystic fibrosis. Dr. Gadi was the first doctor to run a full blood panel which all other doctors had not and realized her pneumovax shot never took. Once she was inoculated our nightmares ended. In addition, I always feel comfortable with the advice he gives our family for our asthma and allergy situations as well as routine sickness. He comes highly regarded by me.

  • A Rare Find
    I suffered tremendously from allergies for many years. I had seen many doctors who weren't able to solve my problem. I began seeing Dr. Gadi in 2002ish for 3 years. My allergies were cured! Aside from his broad knowledge, he has an excellent bed side manner, is great with kids and is a genuinely good person who really cares about his patients! !!!! A rare find.
