Meet The Staff

Drs. Lenz, Sullivan, Gough and Abrahamian realize that we could not provide high-level treatment and service to our patients without our great staff alongside us each day. Many of these people have been with us for decades and we couldn’t be prouder having them as part of our team. 

Our exceptional, friendly staff is our greatest asset. Our dental assistants and hygienists are licensed professionals who pride themselves on staying on the cutting edge of dentistry and patient communication. They are excited about what they are doing, have high standards of quality and integrity, and are motivated to achieve the best results for our patients.

Our dedicated and motivated staff has one primary goal—your utmost comfort! We feel it’s important that you understand the treatment that you’ll be receiving so that you can relax during the procedure. Our staff is eager to answer any questions regarding your dental care. Please feel free to share with us your needs and concerns.
