Although no one likes to go to the doctor or dentist, we strive to make your visits with us as comfortable and pleasant as possible. We strongly believe that our patient’s comfort is an important part of quality dental care.

We believe that your right to choose a dentist is an important freedom. We work closely with your dentist, but a referral by a dentist is not required to visit our office. We also welcome referrals from patients and friends of the practice.

We are extraordinarily proud of our staff, which is comprised of caring and dedicated professionals. They ensure that the patient’s therapeutic and administrative needs are met as efficiently and smoothly as possible.

Our goal is to make you feel comfortable and relaxed. We are here to listen to your questions and concerns and to help provide solutions leading to your better health.

Happy Patients

Dr Phan and Dental Assistant Jane were really Pros from start to finish. Jane was absolutely hilarious and very attentive, while also totally professional. Her and Dr. Phan made a great team and were able to solve my complicated wisdom tooth situation and always kept me informed of every risk before proceeding. Thank you!

Dr Beckstead is amazing. I had partial bone loss around one of my teeth and three dentists think that I won't be able to keep it, but Dr Beckstead performed one surgery and saved my tooth. It has been over two years since the surgery and I have not had any more issues with that tooth.

I'm actually looking forward to my next prophylaxis. That's a teeth cleaning, and I never would have believed I'd say such a thing. I want to give a special shout out to Cindy, who did a fantastic job on my teeth AND gave me the tools and knowledge to nip gum disease in the bud. Have you ever heard of a Sulcabrush? I have one now, and it's awesome. Look it up.

Dr. Beckstead and his entire team are exceptional. They provided kind, informative and top-notch care every step of the way. My nerves were immediately calmed when I entered the office and I realized that I was in the caring and experienced care of true professionals. The procedure was flawless, the outcome was terrific and the entire process was pain-free (in every way!).
