New England Dental Wellness 78 Country Club Road, Greenfield, MA 01301

"We had high hopes for this dentist but had to leave. I knew it was time to go when my son got upset at how rude the dentist was to the women he worked with. Plus, the three cavities he filled for me have never felt right since. Super expensive and have to listen to COVID denial. Feels like the dentist has entered his “stay off my lawn!” phase. All the women who work there are awesome though."

"Dr. Mark is the best dentist, hands down. Really talented at cosmetic dentistry and actually knows and understands how health and wellness plays into the health if our teeth. Very lucky to have him in the area."

"Being a licensed healthcare professional, I’ve known for many years that despite my consistently getting great marks from dentists, unresolved dental issues were a big piece of my own health puzzle. Still, knowing that and being able to get proper treatment to resolve it are two separate issues. Last fall, though, I discovered New England Dental Wellness and Dr. Mark Wisniewski, an experienced biological dentist offering exactly what I was looking for: safe mercury (and all metals) removal, biocompatible restorations without metal, and ways and means to treat underlying infections from root canals and suspected cavitations, including providing supportive ozone therapy. Bonus, I like him - and his staff! :-) Over the past six months, I have had all metal (including mercury) removed and have had a first surgery removing an infected root canal and failing aching tooth as well as treatment for two cavitations. At each step, I’ve found my body becoming more relaxed and pain-free, my sleep improving, chronic sinus infections beginning to resolve and more. As a practicing healthcare provider, I can say that to offer the kinds of services Dr. Mark offers, including staying current with the rapidly evolving science and treatment strategies, is not an inexpensive endeavor for the practitioner. Furthermore, insurance lags well behind and will not cover everything. But treatment and results I have experienced and continue to experience here are well worth what they have cost me and I would do it all again in a heartbeat. Thank you, Dr. Mark, Kay and Deb! - Dr. V"

"Wonderful experience! Not something you usually hear about a dental office visit?! Well it’s very true here. Dr. Mark and his staff are exceptional. Warm, welcoming, professional and kind. This is cutting edge dentistry at its best!"

"Dr Mark is the best dentist I have seen in my lifetime. He is skilled, a book of knowledge. He is passionate about the patients overall health. The team is friendly and professional. I highly recommend New England Dental Wellness."
