Dental Hygienist Windham, NH

Shannan Sweezey, RDH


Shannan graduated from Middlesex Community College, Lowell MA, in 1998 with an Associate Degree in the Science of Dental Hygiene and earned a Certificate in Health Careers in 1996. In 2009, Shannan earned her certification to administer Nitrous Oxide and Monitor the use of Nitrous Oxide. This past April 2019, Shannan expanded her skills by obtaining her Local Anesthetic License for both NH and MA. These certifications allow her to provide an extra level of comfort to her patients who have anxiety and fear of the dental office.

Shannan’s dental experience consists of 20 plus years in the dental industry where she specialized in Pediatrics for six of those years, Periodontics for one year, and general dentistry since graduating from college.


Shannan has a desire and passion for dentistry and continually brings the most recent and up-to-date knowledge in her field by keeping up with current protocols and expanding her education. She is very empathetic and strives to help each of her patients reach their optimal oral health in the most comfortable way possible. Shannan enjoys establishing a great rapport with each of her patients and treats them as she would treat her own family.


Shannan grew up in Ashland, MA, and moved to New Hampshire in 1996. She currently resides in Hudson with her family. Outside of the office she enjoys watching football, cooking, music, relaxing on the beach, and going to the movies. However, her most favorite past time is spending time with her three teenage children (one who has special needs of autism) as well as her significant other, Greg, and his three teenage boys.
