      I was so overwhelmed with the knowledge, wisdom and guidance given to me by Dr Ispas, as I navigate wether to take the booster. Because of severe reactions to the vaccination I needed an expert to take next steps with me. Dr Ispas is so current on her knowledge and well read on the reality we face daily with Covid, immunology and allergies. Choose her for your care you will be in safe hands with wonderful outcomes for your health.

      Dr. Ispas-Ponas is one of the most competent doctors I've ever had the pleasure of visiting. I had reached a dead end with my other allergist. He couldn't figure out what was making me have an anaphylactic reaction. I switched to Dr. Ispas-Ponas and she did a fantastic job pinpointing exactly what was causing my reaction. She's also a wonderfully caring person. You really feel her sincere interest in your health when you visit. I highly recommend her and her entire staff - all fantastic!
