Shinera, RDH, Regional Team Leader

Hello, my name is Shinera. I am a Registered Dental Hygienist as well as a Regional Team Leader. I am also trained to practice Orofacial Myofunctional Therapy (OMT). I joined the practice in 2006 and instantly fell in love with pediatric dentistry. I have two children of my own and they have given me a new perspective on what is needed from me to give my patients the best experience possible. Dental anxiety begins at a young age and this is something I plan to alleviate by guiding children through their visit and giving them the comfort, they need and deserve. With our amazing doctors and team, I am able to help lead our patients towards a healthy and successful adult life. My goal for this upcoming year is to continue to support and motivate the clinical team to be the best we can be. I am also exhilarated about bringing OMT to our patients and families. I am blessed to be a part of such a wonderful team. Being a dental hygienist is truly so rewarding and I absolutely love what I do.

Hi! I’m Lisa, Registered Dental Hygienist.  I started filling in at the office on and off for 17 years and was finally able to make it my permanent home in July 2020. My love for dentistry started at the young age of 14 with my first job being a dental assistant.  I studied at University of Rhode Island and graduated with my dental hygiene degree from SUNY Orange in 1998.  I was able to pursue my career, get married and have three children.  I have over 14 years’ experience working with children and special needs patients. My dedication and love for children gives me the drive to make their experience to most pleasant possible!

Hi! My name is Amanda and I’m a Registered Dental Hygienist. I was born and raised in the San Francisco Bay Area, but made the transition out here to the Hudson Valley during the summer of 2019 and joined the VPD shortly after. I’ve always had a passion for dentistry and started my training right after high school as a Registered Dental Assistant before going into dental hygiene school. I graduated from Foothill College in Los Altos, CA in 2014 and immediately began working in a prosthodontics office in San Francisco for five years. While working in that specialty was wonderful, it has been a refreshing transition to work with pediatrics.  I’ve enjoyed every minute of learning and working with our team and most all, you, our patients! When you don’t see me here, I’m spending time with my family, friends, hiking, volunteering, and sightseeing this beautiful state. I can’t wait to meet you!
