I started my first dental assisting job in 1996 right out of highschool with no experience. During that job, I went to school and got my x-ray license, my CDA (Ceritified Dental Assistant) certificate and a few years later, I attended Manor Junior College part time while working full-time to earn my EFDA (Expanded Functions Dental Assistant) license which allows me to place fillings and make crown temporaries amongst other important jobs. At work I truly enjoy getting to know the patients and hearing their stories, they make each day different and special.

During my non-working days, I'm a mother to 3 awesome kids that were born in 2003, 2007 and 2013. I've been happily married to my high school sweetheart who I've been with since 1993. One of my favorite things in life are spending time with my family. Our favorite vacation spot is Ocean City New Jersey where eating Mack and Manco pizza is always our first stop.

I played soccer from the age of 4 until I had my first daughter. Now that my playing days are over, my sports life consists of watching my daughters play softball for Sacred Heart and watching the Philadelphia Phillies, Flyers and Eagles.


Michelle Johnson

Wrighstown Office Manager, Lead Dental Assistant

Michelle is The Smile Center's Dental Assistant Team Leader and has been with the practice since 2010. Aside from her general dental and periodontal specialty assisting duties, Michelle is one of three assistants responsible for the design and fabrication of our office's state of the art same day all porcelain crowns. She is also one of our Zoom whitening technicians and manages the practice's clinical supplies. Michelle is definitely a "go to" person for all of our departments.

I graduated from West Liberty University, WV in 1996 with an A.S. in Science in Dental Hygiene, and my Bachelor's Degree in Dental Hygiene in 1997. I have been doing dental hygiene for 19 years. I am proud to be a part of a high quality, ethical practice with a multitude of very talented professionals. I enjoy working with both special needs adults and children and will do whatever it takes to make them comfortable in the dental office! In 2011 I earned my Certificate for Local Anesthesia Administration! During my career, while continuing to practice clinically, I branched out and spent 5 years as a Dental Health Educator through the Dept. of Health and Senior Services in Burlington and Camden County . This was a great experience as I was able to outreach to high risk communities providing school assemblies, parents training and dental health education in a variety of community settings. At Burlington County College Dept. Of Dental Hygiene, I spent a few semesters as a Clinical Instructor, and taught a few courses at BCIT, in the Dental Assisting Program on my days off from the office.

I think it's important for our profession to have a positive role in the community and I have organized our participation in Give Kids A Smile Day the last five years, which we donated over $60,000 in dental services to underprivelaged children. I facilitated our participation with the Head & Neck Cancer Alliance to provide Free Oral Cancer Screenings for Oral Cancer Awareness Month for the public as a non-profit site volunteer. I am happy to give a Girl Scout Tour or speak at a community function. In my spare time I also run our Facebook page, admin our website and do marketing material..

I have been married for 16 years and have 3 beautiful girls, Maija, Isabella & Sophia. I have 3 dogs, all are rescues from the shelter. My girls love to go to the beach, play field hockey, musical and help with various cancer charity events. I love to run, have run 13 marathons and four ultra marathons and I love to be outdoors in nature!
