Mark Horton, MD, who specializes in Pain Management, is one of the Cheshire Medical Center physicians named one of New Hampshire Magazine's Top Doctors for 2024.

Pain management can mean many things to many people. To me, it means helping patients find the tools and treatments necessary for them to achieve more comfortable and more functional lives.

Thirty of the 248 Dartmouth Health physicians across 58 specialties recognized in New Hampshire Magazine's "Top Doctors" survey care for patients at Cheshire Medical Center.

Please join us in congratulating the physicians recognized. Whatever challenges our doctors faced this year, nothing stopped them from providing exceptional care across the region. There's no better time to say "thank you." Our community wouldn't be the same without you.

New Hampshire Magazine partners with the national research firm Castle Connolly to distribute surveys to every licensed practicing Granite State physician. The physicians are asked to nominate specialists who they would recommend to friends and family for treatment. Those receiving the most nominations are named as the top doctors and represent leading physicians in their respective specialties.
