Great !

I cannot say enough wonderful things about Dr. Gary Kleiner. From the moment we walked into his office, I felt completely at ease knowing my 7-year-old son was in the best hands. I had so many concerns and questions about allergies, testing, and how to best care for my child — and Dr. Kleiner took the time to thoroughly explain every single detail in a way that was both reassuring and easy to understand. He never rushed us and made sure I felt informed and confident about each step. His calm, kind, and patient manner truly stood out — it’s rare to find a doctor who combines such deep expertise with genuine compassion. My son felt comfortable and even curious during the process, which says so much about Dr. Kleiner’s gentle approach with children. I left the appointment feeling relieved, supported, and educated. I highly recommend Dr. Kleiner to any parent seeking a knowledgeable, thorough, and truly caring allergist. He’s a gem in his field and someone who clearly cares about the families he helps. The nurses are equally exceptional at this practice also - I am truly impressed with the level of care. This is the type of care every single patient should receive in 2025 and beyond!!! #futuristiccare

The initial consultation by the other doctor was excellent. I felt that her exam was thorough and my concerns were heard and addressed.

Dr. Gary Kleiner is a godsend to me. His knowledge, expertise, and caring is in a league of it's own. Dealing with a primary immune deficiency is complicated and occasionally scary, and Dr. Kleiner always takes the time to answer all my questions, and to inform me of relevant state-of-the-art research, testing, and treatments. When people ask me what I like best about Florida, Dr. Gary Kleiner.

Dr. Kleiner is always very professional and knowledgeable about our condition and what we are going through.
