Dr. Khanna and all the staff at his office are absolutely amazing. I felt welcomed from the moment I walked in and was greeted by the receptionist. I didn't wait long before being seen by the nurse, Dr. Khanna or the nurse who conducted the allergy test. Dr. Khanna walked me through the entire appointment, and explained to me what was going on or being done. He calmly explained what my options were, and listened to what I had to say. I definitely recommend him, and his staff.
