Dr. Keller DOES NOT offer laser hair treatment and never has. He prescribes propecia for his patients in three month intervals to make sure no side effects are occuring with his patients. Dr. Keller truly cares about his patients and would never try to scam anyone!! The other comment must have him mixed up with someone else. Dr. Keller is located at 740 N. Waukegan Rd.,SUITE 106, in Deerfield IL.
