Dennis Davis D.M.D. M.S.

Board Certified Periodontist

I am a Diplomate of the American Board of Periodontology.  I am well trained in all phases of non-surgical and surgical periodontal therapy.  My undergraduate 
studies were completed at Florida State University, where I received a Bachelor of Arts degree in Biological Science. I went on to receive my Doctor of Dental Medicine degree in 2002 at Nova Southeastern University.  After spending several years in general dentistry, I completed a Dental Implant Fellowship at Southern Illinois University. I obtained a Certificate in Periodontology from the University of Florida in 2007. 

The experience I had as a general dentist allows me to work closely with referring dentists to establish a dental treatment that best serves patients’ needs.  My rapport with patients puts them at ease as I review each treatment plan.  

I contribute to the dental community by holding monthly study clubs where I facilitate continuing education for general dentists. 

I am an avid outdoorsman and enjoy hiking, running, biking, and swimming.  I live in Ocala with my wife and two daughters.
