Practice Staff

The following professionals make it possible for Dr. Gauthier to meet achieve and exceed your dental health care expectations:



 Penny, Head Dental Hygienist

Penny has been with Dr. Gauthier since 2001. 

She began her dental career over thirty years ago.  Penny graduated from Pensacola Junior College’s dental hygiene program in 1995, so she now has over sixteen years of experience as a hygienist.  Penny has two adult daughters who both reside in Tampa.  She recently welcomed her first grandchild, a baby girl, to her extended family.  In addition to doting on her granddaughter and dog, Penny participates in local cancer awareness events because she is a two-time cancer survivor.







Chris, Head Dental Assistant - Details (and photo, if he'll let us take one) coming soon!




Greg, Office Assistant & I.T. Specialist 

Greg (a.k.a. "Gregory") became an employee of the practice in August 2011.  He is Dr. Gauthier's son.  Gregory is a 2011 graduate of Tampa Catholic High School and is getting close to completing his A.S. at Hillsborough Community College.  He has played ice hockey since he was six years old, including several years in a travel league and one year of Juniors. He currently plays in a local adult recreation league and plans to continue his sports career when he studies physical therapy at USF or Florida Gulf Coast University. 



Lois, Business Specialist

Lois has been with Dr. Gauthier since 1985, but she only became an employee of the practice in August 2011.  If you are wondering about the time difference, it is because she married Dr. Gauthier while he was still in dental school!  Lois has a B.S. in Engineering from Marquette University (Milwaukee, Wisconsin) and an M.B.A. from the University of South Florida (Tampa).  She is also a graduate of the diakonia TM program.  As part-time business specialist, Lois puts her M.B.A. studies to work for the practice.  She also continues to work full-time as a program manager for a state environmental agency and serves as a Deacon in her church
