Education: Mercy College

In 2008, at the age of 49, I decided to go back to school and pursue my passion with animals, becoming a Licensed Veterinary Technician and graduated Mercy College in 2011. My husband Neal, and my kids Pamela and Brandon were my biggest supporters.

I love what I do. My goal is to always bring a positive attitude and a smiling face to every appointment so both my patient and client have a comforting and welcoming experience. I’m also a Fear Free Certified Professional, helping to create less Fear, Anxiety and Stress for our patients.

That is my objective each and every day.
