Tippit Dental


It's More Than Dentistry. It's Family
  • Memorial: Fast-Paced Dentistry. Small-Town Feel.

    In the booming area of Memorial, there is so much to do. From endless shopping to countless restaurants and entertainment venues, life is unequivocally fast-paced. At Tippit Dental Group, we understand that. This is why we have our precise scheduling system down to a science and our dentistry down to an art. Part of excellent patient service is respecting every patient’s time. Despite the fast pace, our office and dental team provide a small-town feel and a relaxed atmosphere for every patient, every time.

  • Home Of Where It All Began

    It all started in Memorial, stretching all the way back to 1979. Part of our long-standing tradition is to treat everyone who comes into our office, not like a patient, but like a family member. Tradition and family values are what drives our pursuit of dental excellence. When you come inside our dental office, you'll be stepping outside of the hustle and bustle of city life and into a laid back atmosphere where you can feel right at home.

Tippit Dental Group: Since 1979

Tippit Dental Group has been serving the Memorial area and Greater Houston residents since 1979. Dr. Nathaniel “Tip” Tippit opened his doors with the concept of providing excellent dentistry, while establishing long-lasting friendships with every patient. This devotion to his patients and his treatment of every employee as if they were family created the Tippit Family model. This model has been the foundation for the success of the Tippit Dental Group, which now has four locations, including Cypress, Brenham, and Bellville.
