Dr. Koehler is an excellent Periodontist! I became a patient of his when he first started his Periodontal practice in a small upstairs office. Steve treated me for a total of seven years, and his treatment was so gentle and caring. The office manager at that time (lady in red) was so sweet and compassionate - They were like family. Although there were some problems towards the end of my treatment, it was sure nothing they had done wrong. Though I don't require treatment anymore, I really miss Dr. Koehler ( it kind of reminds me of a Neil Diamond song).
