Dr. Shaina A. Holiman Darmont, DDS

Dr. Darmont joined the Plaistow Dental family as a General Dentist in June of 2015 after graduating from The University of Maryland in Baltimore. However, her career at Plaistow Dental truly started when she was probably around 4 when her father, Dr. Holiman, purchased Plaistow Dental.  Growing up, Dr. Darmont had the unique opportunity to observe her father practicing dentistry by just hanging around the dental office and eventually assisting chairside.  She enjoyed getting to know and serving the residents of Plaistow, NH and the surrounding towns so much that she decided to go into dentistry and join the practice where she grew up. She has enjoyed working closely and receiving mentorship with her father.   

Over the years since graduating dental school Dr. Darmont has had the opportunity to work side by side with some of the best practitioners in Boston at Bicon Dental Implants, where she received extensive training in placing and restoring dental implants.  Dr. Darmont enjoys practicing dentistry and taking continuing education courses at any opportunity she gets.  She spends her free time practicing hot yoga and exploring New England with her husband Francis and dog Kenji.
