About Dr. Marshall S. Michaelian

San Mateo’s Central Park neighborhood keeps things rolling with specialty care close at hand. If root-canal treatments or tooth-saving procedures sit on your agenda, Dr. Marshall S. Michaelian runs the endodontics practice at the top of the Ellsworth Medical Tower.

The office sits at 100 S Ellsworth Ave #801—a straightforward location inside a nine-story building north of Fifth Avenue. Patients can tap (650) 344-0299 to arrange focused endodontic care such as nonsurgical root canals, endodontic retreatment, surgical root-end procedures, and treatment for traumatic dental injuries. Internal-bleaching and apexification are also handled here when needed.

Endodontics delivers precision when nerves or roots require meticulous work. The field pivots on micro-instrumentation and magnification to preserve natural teeth. When canals are fine or previously treated cases stall, specialized re-treatment techniques reopen the path to healing. The specialty quietly underpins a lot of general-dentistry outcomes you never see.

Driving in? Use the map for exact navigation: https://www.google.com/maps/place?ftid=0x808f9e7127e66b57:0x279a89468ac1642f Central Park’s side streets fill quickly around lunchtime, so leave a buffer for parking or rideshares.
