I was in this office a few times having only seen PA's.   They were nice and helpful, but not solving my condition so I asked to see a MD.   Dr. Kasunic was the one that saw me...he was sexist "you know how we talk to blue eyed blondes" and demeaning to me "I have the same cough, don't worry about it".   After explaining my 10 yr condition and medication that worked for me, he determined I didn't need that same medication to recover...I tried his way and two weeks later am ever sicker.  I called and appealed that I needed that additional medication and they refilled my antibiotic which wasn't working...I would NOT recommend him to anyone, let alone any woman.
