Dr. David Rosania

Hi, I’m Dr. David Rosania, and I am one of the most experienced surgeons in the Seacoast and the state.

I am a Board Certified Periodontist and was the first surgeon in our region to place a modern-era dental implant over 30 years ago, and I have placed several thousand since then. I have also performed well over 20,000 periodontal surgical procedures. I am excited to combine my experience with the state-of-the-art training my daughter Amy has received at the University of Pennsylvania and the University of Connecticut, two of the most highly ranked dental programs in the nation. I am committed to treating my patients with dignity and with providing a personalized experience as free of stress as possible. There is a good chance that you know one of my patients, and if you ask around I am confident that they will confirm this.

I received my education at Tufts University (B.S. cum laude in Biology and Psychology) and the University of Connecticut (D.M.D. and Specialty Certificate in Periodontics), most recently earning a M.S. in 2008 (again at Tufts University). I am a past President of the Rockingham County Dental Society. I founded a 30-year-long dental study club and author The Perio Perspective, a newsletter for local dentists and hygienists. From 2008-2015 I indulged my love for teaching at The Governors Academy, where I taught Biology, Physics, Chemistry, Anatomy and Physiology, and Environmental Science, while continuing to practice Periodontics and Implant Therapy. I continue to cherish my three grown children, two granddaughters, and Pam, my wife of over 40 years. My hobbies include triathlon, electric guitar, studying science, psychology and philosophy, and trying to keep up with Amy running and skiing.

Drs. Amy and David Rosania were both included on the National Consumer Advisory Board’s list of America’s Best Dentists for 2017-2020.

They were also voted onto New Hampshire Magazine's list of New Hampshire's Best Dentists by their dental colleagues from 2017 to 2020.
