Office Manager

I started in Denistry in 1999 in New Fairfield, CT. I’m thankful, looking back, that I started in such a great office! I have been with Dr. Castor for 11 years and love working with such an amazing and dedicated team makes my job easy. I love traveling the world and interacting with other people and cultures. I have 2 fur babies, Abbylola and Nugget.


Treatment and Insurance Coordinator

I have been in the dental field for 20 years and with Dr. Castor for 11 years. My favorite part of my job is hearing and seeing how happy patients are when they leave! I love what we do and it shows in how we care for our patients. I understand we treat our patients in the same manner we want to be treated. I handle all dental insurance and I will always be your advocate. When I’m not at work, I love spending time with my husband, my son and my dogs, Cooter and Lilly.


Dental Assistant

I started my dental career in 2007 and have worked with Dr. Castor since. The best part of my job is witnessing the happiness that radiates from patients as we positively affect their lives through perfecting their smile. When not working, I spend time with my husband and my two dogs, La Kelly y el Jack!


Dental Hygienist

Janis has been a Dental Hygienist since 1983 and has worked with Dr. Castor for 8 years and takes pride in being part of an outstanding team member at Dr. Castor’s Family Dental Practice. She looks forward to reminiscing with old acquaintances and making new friends. She believes everyone deserves the same quality of care and is always ready to provide education on positive oral hygiene. While away from work Janis and her husband Chris enjoy spending time with their 3 children and 2 grandkids. You may find Janis on her 100 year old family farm in La Grange, where she was raised, working alongside her 4 siblings-carrying on the family tradition of making pork or deer sausage in the old smokehouse. In addition to cooking, she enjoys bargain hunting for antiques or great deals at the local business’.
