Our team here at Alton Bay Dental are proud to be a part of the Alton community and our goal is to provide the highest quality of comprehensive dental care for the whole family. We strive to help each patient develop a clear understanding of their oral health and the importance it has on their overall health.  Treatment plans are specially tailored for each patient as it is important to us that each patient fully understands their treatment options both clinically and financially. 

Our team of professionals including Bryana, Katie, Bri (CDA) and Mercedes (RDH) are dedicated to our practice and our patients.  Continually training in all aspects of dentistry, our team is there every step of the way to walk our patients through all treatment recommendations as well as dental insurance and payment options. 

Curtis Thibeault, DMD

Dr. Curtis Thibeault completed his education at the University of New England College of Dental Medicine.  He graduated among the top in his class while being inducted into the Omicron Kappa Upsilon Honor Society based on high scholarship and character. In 2018, Dr. Thibeault also received the Clinical Excellence Award for his distinguished clinical skills throughout dental school. He began his dental career here in NH in a private practice setting at Alliance for Dental care providing dental care for the greater Rochester Area. 


Eager to achieve his dream of owning a dental practice, he was fortunate to meet Dr. Manuel Posada and his truly remarkable dental team. Although Dr. Posada is moving on to the next chapter in his career, Dr. Thibeault and our team here at Alton Bay Dental will continue to provide exceptional care tailored to each individual patient's needs in a comfortable and calm environment.

Dr. Thibeault is thoroughly passionate about the art of dentistry and he along with his wife, Jayne and daughter, Aubrey are beyond grateful and eager to be joining the Alton community.


Mercedes Moulton, RDH

I have been a Dental Hygienist for nine years. I graduated from New Hampshire Technical Institute in 2011 with an Associate degree in Dental Hygiene. I am licensed in New Hampshire and certified to deliver local anesthetics.  As a Dental Hygienist, my focus is to provide the highest quality care to all my patients, while making hygiene appointments a positive and comfortable experience.
I have been married for seven years and I have a four year old son. In my time off, I enjoy spending time with family and friends.


Bryana Granquist

After graduating from college in 2015 with a double bachelors in business, I returned to my hometown of Alton, NH, where I began working for Alton Bay Dental. Through the past 5 years, I have come to love and appreciate the different aspects of dentistry. As the Patient Care Coordinator, I answer your calls, help you understand your insurance information, and schedule your appointments. I have been married for 3 years and just recently had a son in January of 2020. In my personal time, I love being with my friends and family.


Katie Anstice

Originally graduating from Great Bay Community College with an Associate Degree in Veterinary Technology and working several years in the field, I decided it was time for a new adventure. At the beginning of 2018, I was inspired to make a career move into the field of dentistry...for humans! Alton Bay Dental quickly added me to their team and began my training as a Dental Assistant. Fast forward two years and I’m proud to say I’m on my way to becoming a Certified Dental Assistant and currently have over 2,400 hours of chair side dental experience. I look forward to continuing to grow as an assistant while serving the wonderful community of Alton, NH. In my free time I enjoy outside activities such as hiking, paddle boarding, and boating with my dogs, husband, family, and friends.


Bri Hughes

I have been a dental assistant since 2014 now, and wouldn’t change a thing. I’m very passionate about my job and all it entails, including continuing education to further my skill set, you can never know it all! I love being able to interact with my patients every day and help make their experience at our office a relaxed and enjoyable one. I recently got married last fall and have an 8 year old step son who keeps us on our toes along with our 3 year old mini australian shepherd. In my free time you can find me at the soccer fields practicing with my son, out on the trails 4wheeling with friends or on a boat somewhere.
