Amazing dentist - and very highly regarded by the old guard of retired dentists in CO. Dr W. is definitley on the Colorado Dentists "A List" - and ALL OF MY FRIENDS go to him now. I have been a patient of Dr. Dan for over 20 years - and even brought my elderly parents to him when they moved to CO. He is kind and professional and really cares about the ongoing health of his patients. I also love the fact that he doesnt suggest unnecessary treatments - he even told my 85 year old father that "Giving him a 30 year old's mouth was probably not necessary" and said this in the most kind and respectful way. My dad got quite a chuckly out of that. Dr. W is very simply, the best dentist in Denver.
