An Endodontic Specialty Practice


“Nobody wants to get a root canal.  We’re here to show the power of kindness, efficiency, a beautiful space, and clinical excellence in shaping the experience.  And we hope you leave our office feeling like we’ve made a positive impact on your day.”                             

                                                                                                         Dr. Sarah Martinelli


Dr. Sarah Martinelli is a Board Certified Endodontist.  She founded Shire City Endo in the spring of 2021 with the goal of creating consistently positive patient experiences.


As an art history and math double major at Williams College, she pursued work at an art gallery in New York City following college graduation.  Her persistent interest in science paired with her artistic sensibility ultimately brought her into the dental world.  After graduating cum laude from the Harvard School of Dental Medicine, Dr. Martinelli attended her endodontic residency at Virginia Commonwealth University where she served as chief resident.


Dr. Martinelli was able to find a wonderful balance in dentistry and design when she created Shire City Endo.  It is an office full of natural light and art where she enjoys practicing with a discerning eye for detail.   She is fortunate to have an ambitious team of staff just as focused as she is on creating a seamless experience for patients and referring dentists.


Dr. Martinelli shares her home in Richmond with her husband, two children, two mastiffs, and a healthy dose of chaos.  


And by the way . . . local artist Rowan Willigan has left her mark at Shire City Endo. Her original works are on the walls, and they are reason enough to come visit us.  She also took all the photos on this site. 


Endodontists are dentists who have completed additional years of training to specialize in treating diseases and injuries of the soft tissues inside a tooth (dental pulp).  They are skilled at diagnosing tooth pain, discussing the best approach for saving your tooth, and providing root canal treatment and other treatments to help maintain a tooth.


Dr. Martinelli provides a range of endodontic services including:


Root canal therapy

Endodontic retreatment

Endodontic surgery

Treatment following trauma

Treatment of cracked teeth

Cone Beam Computed Tomography
