Enhance and Protect Your Sensational Smile

Meet Dr. Dat Pham

First thing you need to know about Dr. Dat Pham, founder of Grand Smiles Dental in Katy, is that he is soft-spoken and calm, which is important when he’s about to perform a dental procedure on you or your loved one. With experience and knowledge he makes you feel at ease when you sit in his chair. He explains every aspect of your procedure to you before he begins.

For all you Buckeye fans, Dr. Pham earned his dental degree at Ohio State University in 2005. Before hearing his calling as a dentist, Dr. Pham graduated from the University of California, Los Angeles’ Civil Engineering program. Originally from Vietnam, he is proud to call the United States his home for over 25 years. He has lived in many cities across our great country, finally settling with his family in Katy, Texas. He and his wife, Jessica enjoy being a part of this community. Their children, Yvonne and Alex attend public school in Katy. Dr. Pham, also, loves salt water fishing, so you might find him with his family on a fishing pier somewhere on the Texas Gulf Coast. One more interesting thing about Dr. Pham is that he rides a motorcycle so on clear days don’t be surprised if you see his bike parked at the office.
