Dr. Williams has been my primary care physician for twelve years. He and his staff are simply the best! He is so good at explaining things, at listening, at coming up with a "plan of action" when needed, at communicating promptly results of tests that were ordered, at recommending specialist when needed, I do appreciate him and highly recommend this practice.

Dr. Williams has been very responsive to my medical needs - explaining situations that I can understand - and answering my questions..initially I consulted him years ago on thyroid condition and he - unlike many - was open to alternatives - even suggesting as he is pragmatic rather than doctrinaire - preferring what works for a patient

I have been a patient of Dr. Williams for more than 10 years. Dr. Williams always takes the time to discuss my symptoms so that he provide me with the proper treatment. He also explains why the treatment is appropriate. I recall an experience when I an unusual problem. Dr. Williams excused himself for a few minutes and came back with a medical book and asked if the symptoms listed were what I was experiencing. The treatment he prescribed was right on. I really appreciate his thoroughness.
in Denver, CO |
I visted Dr. Williams on 8/03/17 to obtain medication prescriptions and to submit blood & urine samples, as I typically provide every 6 months. He also checked my body for signs of problems and asked me if I was experiencing any new adverse symptons. Dr. Williams is very caring and thorough, with an excellent "bedside manner" and he's the best doctor I've seen in many years to take care of my general healthcare needs. He called on the following Sunday afternoon with my lab results. A great MD!

Dr. Williams is THE BEST a doctor I've been under the care of! After being diagnosed with a complex disease, he has supported my care with other specialists and seen me when I have difficulty with regular health issues or other needs. I was over medicated years ago which could have resulted in a seizure or death. Dr. Williams called me EVERYDAY and checked on me until I successfully titrated off the medication. Anyone would be lucky to have him as their physician! He truly is a caregiver
