I was very impressed by Dr. Farhadi's professional and through consultation with him. I have had issues for about 2years now. And the previous dr. Hasn't helped my condition or give me direction. Dr Farhadi got right to it with test and advise. Which has made me feel so much more secure. Thank you Dr Farhadi.
