A Personal Note from Dr. Tom

I've known both Dr. Grube and Dr. Villarreal for many years and without a doubt they are not only exceptional human beings, but also are extraordinarily well qualified, skilled, experienced, and caring dentists and health professionals. Dr. Grube is unique in that she is also a Doctor of Integrative Medicine, a combination that is rare in dentistry. This combination is extremely important because of the direct and important relationship of oral to overall health.

Her concern for her patients health, her ongoing training in holistic, cosmetic, and traditional dentistry; along with her commitment to safely remove amalgam fillings makes her ideally suited to remove and replace them.

Because of her medical background and her ongoing training and dedication to biological and mercury free dentistry, I highly recommend her to anyone seeking a holistic oriented dentist for all their treatment needs. I consider her to be a very special person, physician, and dentist and don't know if you will be able to find a more knowledgeable and dedicated holistic dentist anywhere.

I am especially impressed with both doctors dedication to mercury safe dentistry as it is such an important part of oral and overall health. I encourage you to visit their informative website to learn more about them and their philosophy of biological and health focused dentistry. When you visit their office, please tell them where you found out about them and say hello to them for me. Thanks!
