Registered Dental Hygienist

Originally from Cuba, Gisselle moved to the US in 2011 at the age of 19 and resided in Bridgeport, where she began her studies to pursue a Dental Hygiene career. Her interest in dentistry was built back in Cuba. Being the daughter of a dental professional, Gisselle’s love and passion for dentistry were instilled at a very young age. Her interest and desire in helping people guided her in making the right decision to become a dental hygienist. Gisselle attended Housatonic Community College and later transferred to the University of Bridgeport, where she graduated with a Bachelor’s Degree in May of 2017 from the Fones School of Dental Hygiene.

Gisselle believes everyone deserves access to good dental care, and ensures parents and kids have a great dental experience, as well as the best care possible. Her main goal is to educate patients on the importance of preventive dental care so they can preserve a healthy smile and overall health. In Gisselle’s free time, she enjoys traveling, dancing, hiking, and spending time with her family and friends. Gisselle has been part of our team since November of 2017.

Front Office Manager

Michele is from Stamford, CT, but she also spent a short time living in Gary, IN. Michele attended business school here in Connecticut and worked for several companies for a long time.

Michele took a chance, and 19 years later, she works as the Office Manager/Front Desk at Riverwalk Dental Care. With Michele’s experience and knowledge of dental insurance policies, she is a great asset to patients and the team. When she's not working, Michele’s favorite activity is spending time with her son and family.
