Therese Susienka, DMD, FAGD

Dr. Therese (pronounced "Teresa") is the founder and General & Cosmetic Dentist of Pleasant Valley Dentistry. She established this office in 2017 after working in two family practices in central Massachusetts, with a desire to offer a dental experience that merged her passion for cosmetics and comprehensive dental healthcare. She has infused her thorough nature into the philosophy of Pleasant Valley Dentistry, where all care providers are passionate about spending time with each of their patients, getting to know their specific needs, and providing meticulous dental care.

Dr. Therese has a strong commitment to professional growth, and spends much of her free time traveling for advanced dental training with internationally renowned mentors in the field. Since earning her degree, she has averaged well over 100 hours of advanced continuing education every year, an amount that far exceeds the biennial requirement of 40 hours. Dr. Therese was awarded her Fellowship in the Academy of General Dentistry in the summer of 2020, a title which requires 500 hours of continuing education and an exhaustive examination, and is only currently held by 6% of dentists nationwide. She is currently in pursuit of her accreditation with the American Academy of Cosmetic Dentistry, a prestigious recognition only awarded after passing a written and oral examination and having numerous cosmetics cases reviewed by a selective board of cosmetic dentists. She also has a passion for service, and has traveled on multiple mission trips to provide dental care to poverty-stricken communities in Central America. 

Dr. Therese was born & raised in southern New Hampshire, but has called Massachusetts her home for nearly 15 years. She currently resides in Sutton with her husband Michael, their son Oliver, three cats, and several chickens. In her free time, Dr. Therese is often spending time with family locally, or in New Hampshire, and enjoys yoga and gardening.  

Dr. Therese is an active member of the American Academy of Cosmetic Dentistry, the Academy of General Dentistry, and Spear Study Club.
