Dr. Michael R. Coppe

Dr. Michael R. Coppe is passionate about pediatric dentistry. "When I was in dental school, I did an extensive study in Sweden; I was interested in public health, and I visited clinics all over the country. The kids were great! Even if I didn’t know their language, I learned I could communicate with them with no trouble.”

Since he was 11 or 12, there was never any question what kind of dentistry Dr. Coppe would practice – pediatrics because he liked the clientele.

Dr. Coppe received his undergraduate degree from Fordham University and was awarded his Doctor of Dental Medicine from Harvard University. Along with his post-graduate training in Pediatric Dentistry from Children's Hospital in Boston and Harvard School of Dental Medicine, he also earned his Doctor of Medical Science Degree in Oral Biology from Harvard University.

Many who know Dr. Coppe – patients and friends alike – know his passion for history, especially 18th century, local history. He was a Colonial reenactor for a long time, and several years ago, he joined the British Tenth Regiment of Foot to reenact the April 19th event on the Lexington Green as a Redcoat. Dr. Coppe has a number of other hobbies including sailing and model trains.

If he could offer dental advice to parents or to patients, Dr. Coppe would say, "Take care of your teeth. Remember to floss and brush and visit us twice a year.”

Carolyn Coppe headshot

Dr. Carolyn Coppe

Dr. Carolyn Coppe knew she wanted to be a dentist since she was a small child. "I grew up in this very office and was always aware of how happy everyone was that worked here. It was an easy decision to make". Carolyn completed her pediatric dental residency at University of California, San Francisco in 2008, after graduating from the Harvard School of Dental Medicine.

The town of Lexington has been a home to Carolyn since she was 8 months old, and she attended both Hastings and Bridge Elementary school before graduating from Lexington High School. Growing up, Carolyn was a member of the Hayden Precision Teams and still proudly wears the label of "Haydenette". Like her father, Carolyn enjoys sailing and can remember attending and participating in the reenactments held on Patriot's Day.

After graduating from dental school, Carolyn accepted the opportunity to do research at the National Institute of Dental and Craniofacial Research in Bethesda, Maryland. It was there that she explored a growing interest in work on dental stem cells from primary (baby) teeth, and she continued this research during her residency at UCSF. Eventually she completed her master thesis on this very topic and was awarded the prestigious Ralph E McDonald Award at the American Academy of Pediatric Dentistry Annual Meeting in 2008. This highly coveted award is given to the resident with the best overall research manuscript and presentation. In 2011, Carolyn passed the American Board of Pediatric Dentistry examinations. The Mission of the American Board of Pediatric Dentistry is to verify to the public and to the health professions that a pediatric dentist has successfully completed both an advanced educational program accredited by the American Dental Association Commission on Dental Accreditation and a voluntary examination process designed to validate the knowledge, application, and performance requisite to the delivery of exceptional care in pediatric dentistry.

Carolyn met her husband, Zach Peacock at Harvard School of Dental Medicine and they continued their training together at the University of California, San Francisco. Zach is an oral and maxillofacial surgeon at Massachusetts General Hospital. Carolyn and her husband are living in Lexington with their sons, Gregory Harper and Trent Stanley.

Chad Sears headshot

Dr. Chad Sears

Dr. Chad Sears has been an orthodontist since 2003 and was Dr. Carolyn's dental school classmate. Dr. Chad and Dr. Carolyn have a long history, they became fast friends during a dental school orientation in the White Mountains of New Hampshire. Although they discovered that they do not like "roughing it" in the wilderness, they did begin a beautiful friendship. Since that fateful trip, Dr. Chad and Dr. Carolyn have remained close and have provided each other the moral support that only best friends can give through all of life's adventures. Dr. Chad began his professional career establishing a successful practice in the heart of downtown San Francisco. He joined our practice in 2015 and provides orthodontic services to our patients including:

  • Clear and traditional metal braces
  • Invisalign (he is a Premier Preferred Invisalign Provider)
  • Jaw growth modification
  • Orthodontics for severe bite problems
  • Treatment for parents too!

Dr. Chad attended the University of California, San Francisco for his orthodontic education where he was selected to be the Chief Resident. He graduated Cum Laude from the Harvard School of Dental Medicine for his general dental program, and Magna Cum Laude from the University of Illinois at Urbana-Champaign for an undergraduate major in biology. He has published his research in peer-reviewed orthodontic journals and was awarded the prestigious Thomas Graber Research Award from the American Association of Orthodontists. He is an eligible Diplomate of the American Board of Orthodontics, and is an Assistant Clinical Professor at the University of California.

Dr. Chad and his partner live in nearby Lincoln with their two goldendoodles, Snacks and Penny. He is an avid chef and loves to eat anything! If you have good restaurant recommendations please let him know.

Dr. Kathleen McCafferty

Dr. Katie, a board certified Diplomat to the American Board of Pediatric Dentistry, completed her undergraduate education at Harvard University and was awarded her D.M.D. from the Harvard School of Dental Medicine. Her post-doctoral training was completed at Boston Children’s Hospital and the Harvard School of Dental Medicine, where she received her Certificate in Pediatric Dentistry in 2015. During residency, Dr. Katie did research to determine if antibiotic therapy caused an increase in molar-incisor hypomineralization in patients with Sickle Cell Disease. She is a big believer in preventative dentistry and loves to help coach families on best oral health practices.

Dr. Katie was born and raised in Sudbury, Ontario, Canada. During her free time, she enjoys being active, playing sports such as soccer, ice hockey, golf, tennis and swimming. In high school, she was a member of the Canadian Jr. National Soccer Team and the Team Ontario Hockey Team. Her love of sports then allowed her the opportunity to play both Division I Soccer and Ice Hockey while attending Harvard University. Unfortunately, she was unable to come away with a national hockey title, having lost in the finals in back to back years. Although she spent many hours involved with athletics, she also focused on her studies, obtaining her BA in Human Evolutionary Biology and ensuring she had all her dental school prerequisites.

When she can’t get outside to enjoy the sun, she loves reading, cooking and, of course, spending time with her husband (who was a former patient of Dr. Mike Coppe) and her children Adeline, Laurel, Emmett and Colleen.

She also enjoys interior design, reading, and spending time with her friends and family.

Dr. Donovan completed her undergraduate degree in biology at Dickinson College in Carlisle, Pennsylvania, and was then accepted to the University of Connecticut School of Dental Medicine where she received her DMD. Dr. Donovan has wanted to be an orthodontist since she was 16 after working for her hometown orthodontist in Maine, so she was very excited when she was accepted to the University of Louisville’s orthodontic residency program. After graduating, she decided to move back to the northeast, which she has always considered home.

She then went on to earn her Doctor of Dental Medicine (DMD) degree at Tufts University School of Dental Medicine, where she graduated summa cum laude in 2021. As someone who is driven by giving back to her community, throughout her tenure at Tufts Dr. Penta was heavily involved in mission-driven organizations both within dental school and beyond, namely leading and serving on the executive boards for the Tufts chapters of the American Student Dental Association (ASDA), American Academy of Pediatric Dentistry (AAPD), and Minds Matter Boston.

Following dental school, Dr. Penta completed her post-graduate training in pediatric dentistry at the University of Pennsylvania School of Dental Medicine and Children’s Hospital of Philadelphia in Philadelphia, PA where she received her Certificate in Pediatric Dentistry. She is currently Board Certified with the American Board of Pediatric Dentistry and is an active member of the American Academy of Pediatric Dentistry (AAPD).
