Donna was incredibly friendly and comforting

I've been a patient of Dr. Willams and Dr Sivie for 20 years and cannot imagine finding a similar operation to even come close to them. Friendly, professional and an excellent atmosphere.

I always have a great experience with everyone at Williams and Sivie. I have been seeing Dr. Williams since I was 3 years old, except for the few years that I was not in DFW. He is the most gentle, kind and generous person! I cannot recommend him enough!

Karen, Dr. Brad and the entire staff did a fantastic job as always. I appreciate the help they gave my family with rescheduling appointments due to last minute work demands.

Sweet lady very informative.

5 stars Customer since 2014

As a three-year patient since moving to Texas, Dr. Sivie and the staff of Williams & Sivie have provided knowledgeable, highly professional services.

Importantly, dental health education has been offered during each visit.

With appreciation, Rita Almon
