      What Impressed Me Most, Aside From Her Professionalism, Is ...

      When Dr. Ispas opened her practice close to my home, I was not aware of her reputation in her specialty. Shortly after, a close friend highly recommended her. Went to my first appointment and have been a patient since. Dr. Ispas is an excellent doctor. What impressed me most, aside from her professionalism, is her kindness and warmth. She truly cares about her patients. I recently told her I feel like a family member, not a patient. I just love her! If she ever has to move, I hope it’s not far away!

      Yet another amazing experience with the most involved doctor I’ve had the pleasure to meet. She really wants to help me figure this out and is going above and beyond what any of the dozens of other doctors that I’ve seen in the past two years. Thanks for caring but most of all for trying to find answers for me.

      It has been my good fortune to have the privilege of meeting Dr. Ispas and being her patient. Not only is she a skilled allergist, but is also a brilliant immunologist. She leaves no stone unturned and has improved the quality of my life. She is an exceptional doctor.

      Doctor Ispas is not only a very knowledgeable doctor but also a wonderful person that feel you comfortable and confident that you are going to get the treatment that you need. After going thru many doctors that couldn't give me a diagnostic, I found Dr Ispas and can not be more happier with the results. Her staff is absolutely fantastic and make you feel welcome the moment you step into her office Maruca
