Dr. Gary Kraus is an excellent surgeon. He did my fusion between L5 and S1, 3 years later I am completely pain free for the first time in my adult life. The only complaint I have is be prepared to wait 1 – 1 ½ hours for an appointment. Part of this is probably because he is very good, but I feel his staff also needs alot of improvement. But I give him 5 stars anyway, and his staff maybe 3 stars.
