Meet Our Team


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, Alycia, Bri (CDA), Katie (Dental Assistant), Cassie (RDH), Shannon (RDH), 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, daughter, Aubrey, and son, Auden are beyond grateful and eager to be part of the Alton community.


Mercedes, RDH

I have been a Dental Hygienist for twelve 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 ten years and have a son. In my time off, I enjoy spending time with family and friends.


Shannon, RDH

As a former certified dental assistant, I decided to continue my education in the dental field and graduated from the NHTI dental hygiene program in 2021. Throughout my schooling, I had the honor of being class president. I am eager to meet new patients and continue to improve the oral and overall health of each individual. Outside of work, I enjoy shopping and spending time with family, friends, my boyfriend of 5 years & five year old goddaughter who always keeps life interesting. I’ve lived in Alton my whole life and am beyond excited to be working here in Alton Bay with the amazing team here at ABD! 


Bri, CDA

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. My husband and I love being outdoors and try to explore and do all the fun things each season offers here in New England with our two kids. You can find us on a soccer field somewhere, riding the trails up north, soaking in the sun on a boat somewhere or chasing the sun from the top of mountains.


Bryana, Office Administrator

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 7 years, I have come to love and appreciate the different aspects of dentistry. As the Office Administrator I assist with scheduling, calls, insurance, and overseeing treatment plans. I have been married for 5 years, have a very active toddler, and a recent newborn in 2022. In my personal time, I love being with my friends and family.


Alycia, Administrative Assistant

After 3 years working in the medical field, I decided to change it up with dentistry. I am quickly becoming to love the dental field and the family here at Alton Bay Dental. As the Administrative Assistant, I answer your calls, help with insurance, and schedule your appointments. In my free time, I enjoy spending time with my husband, our two dogs, family and friends.


Katie, Dental Assistant

After completing my Associates degree in Veterinary Technology, I spent several years working in my field of study at animal shelters and Veterinary hospitals. While practicing in the animal field, I gained an interest in dental health. From there I decided to pursue options working in human dental and landed a job as a Dental Assistant at Alton Bay Dental.

I learned on the job and have now been in the field since 2018. I’m truly passionate about what I do! While I still love our four-legged friends, I’ve chosen my time with them to be more of a hobby instead. I look forward to continuing to learn and grow in the dental field working alongside our wonderful team at Alton Bay Dental. In my free time you can find me chasing my busy toddler, organizing/decorating, surrounded by dogs, or outside enjoying New England’s ever-changing seasons with my family.
