As a professional, my calling is to develop lasting relationships by promoting health and wellness through the provision of dental hygiene care. As a standing member of the American Dental Hygiene Association I encourage and promote the highest standards of education and practice in the dental hygiene profession. Commitment to my patients and their continuing health is practiced by educating myself with the current events, as well as keeping up to date on latest trends and techniques in dental hygiene as we advance as a profession.

A graduate of the Camden County College Dental Hygiene Program in 2004 I was awarded the Hu-Friedy Golden Scaler Award for remarkable skill and talent over the course of my degree.

My professional career began at Dental Wellness of Riverton in October 2004 with Dr. Sanya Sweeney-Fonseca and Dr. Douglas Cohen and I have since continued to care and educate patients as individuals in their specific needs.

Jennifer Mahoney, RDH

Prior to joining the staff at Dental Wellness I graduated from Camden County College Dental Hygiene in 2004 and have been providing dental hygiene care for patients of Dr Sweeney – Fonseca and Dr Cohen since 2006.

When I decided to pursue a career in dental hygiene I envisioned myself working at an office exactly like Dental Wellness: one that gives superior level in quality as well as compassion. I appreciate all of our patients and want to make them happy that they chose to be a part of our family.

When I’m not working I enjoy being a mom to my two children, relaxing on the beach, and being surrounded by friends and family.

Dental Wellness of Riverton is amazing! I have been a patient for years and they have always been SO wonderful and friendly!!! Dr. Cohen is always so professional and nice. Debbie (dental hygienist) takes such great care of my teeth and it's always a pleasure to see her! The entire front desk staff is the absolute best! When I was laid off and lost my insurance, they worked with me to make sure I was still able to get proper dental care. They truly care about their patients and treat us like family! Do yourself a favor and visit them. You won't regret it!

Dr. Sanya Sweeney is caring, warm, and very thorough. Hygienist Jen is super. I'm moving to Florida and leaving this practice is one of my biggest regrets. Each staff member is helpful and caring. When I left yesterday I got a hug from everyone. They use the most up to date equipment and I've never suffered any pain in any of the procedures I've had. Dr. Sweeney bends over backwards to accommodate my schedule, too. They're great!
