      Excellent! Having moved to Leesburg last year I was looking for a new Allergist and based on a review I decided to see Dr. Ispas. So glad I did. Receptionist was very friendly and easy to schedule appointments, lots of good hours and timeslots as well. The office is very convinient in a nice building with many good doctors. The doctor was very through and I never felt rushed. Seems like a good allergy practice. Thanks to Yelp reviewers for steering me here in the right direction!

      This was our first visit and the Doctor was gracious and took a lot of time to learn about my allergy issues. I had bounced around the past couple of years trying to find a great doctor, and I think I have finally done it! The staff was also friendly and nice.

      Friendly staff and doctor. Glad they got me in after I spent the night in ER for an allergic reaction. I will be back soon for testing. Jennie at the front office was great!

      Hands down the best Allergist ! I just moved from Ohio and had to quickly find a new allergist in Leesburg. I looked online and read the reviews for Dr. Ispas and called for an appointment. I was able to make an appointment for the next day. From the receptionist to the nurses to the Doctor all are wonderful ! The place is very busy and in high demand but was full of positive energy. Got a detailed treatment plan and more time was spent on discussing my food allergies then I ever got before! I was quite impressed! Cannot wait to return next week for more testing! I truly appreciate the good medical care.
