After 10 doctors (ENT, Neurologists) and no answers, Dr. Kohan was able to help get to the root of the problem after one visit. His staff is exceptional. I was fatigued from all the lack of answers from previous doctors that I almost canceled the appoint. Thank you so much for the encouragement and support of the staff that ensured me if anyone could get to the root of my problem it would be Dr. Kohan.
