: Becky welcomed me with her big smile and we had a nice talk. She also explained the insurance coverage very well. Yonnie made me feel so comfortable while cleaning my teeth that I fell asleep! Dr Vadnal was his charismatic self. I left very well informed. Jane stopped me just to wish me Merry Christmas. Everyone I saw wished me Merry Christmas!

I wouldn't change a thing. I am not the best patient. I have my hand held by the assistants when in my mind its gonna hurt but it doesn't. Dr Vadnal is the best dentist i have ever had. The ladies in the practice are wonderful. I consider them as family I hope more people join this group as there is no comparison. I have had a dentist from hell, no more. I'm staying right here

: Don't change anything, as long as you retain your current staff and treat new staff the same way. You have me and everyone I recommend to have dental work performed here for life. Thank you.
