Dr. Timmerman is the best MD we have ever had & feel very fortunate to have a primary dr. who is very knowledgeable & competent. We moved out of the area 5 yrs. ago and appreciate his care so much we drive 45 min. to his office.

My doctor was concerned about my symptoms and gave me great care. I know he will follow through until my symptoms are resolved.
