A Letter To Our Wilton, CT Patients

Dear Patients;

COVID19 has changed the world for now and maybe for a long time to come.

At (formerly Dr William Schmid’s practice), we have some exciting changes as well.


We are temporarily practicing at 148 East Avenue in Norwalk, while we construct our NEW location.  Our newly constructed practice will be at 27 Danbury road in WILTON, just down the road from Dr Schmid’s former location, directly across the street from the Little Pub. On the third floor above KAOUD’s.  Don’t worry there is plenty of parking and an Elevator to take you up to our brand-new dental office.

Unfortunately, Dr. MacFarlane has decided for medical reasons to move back to New Jersey.
Please welcome BACK our RETURNING owner:
