I have been working at Mendon Animal Clinic since 2021 as a Client Care Specialist.
As the first point of contact for the client and patient I am dedicated to making sure you feel comfortable and welcome. I enjoy working with our clients and I’m here to support you throughout the treatment process with prompt answers, information and respect. At Mendon Animal Clinic my highest priority is a satisfied & well informed owner. Superior customer service is the hallmark of Mendon Animal Clinic.
I love working with animals and every day I look forward to coming to work to see our four-legged friends! I also love spending time with my husband and two beautiful children, traveling, gardening, horseback riding, spiritual meditation and of course sharing precious time with my cat Punda.

Born and raised in the area, I’ve always had a deep love for animals of all shapes and sizes; wild and domestic. My career in animal care started at Southwick’s Zoo, where I first discovered my passion for working with animals. Over the years, my experience has expanded to dog walking, boarding, and now, as a receptionist at Mendon Animal Clinic, where I’m excited to assist in providing care for pets in my community.
Alongside my work in animal care, I’m also a graphic designer and illustrator, with a particular focus on animals as my subject matter. I enjoy using my creative skills to woo and bring whimsy to life through art and design. When I’m not at the clinic, I love anime, enjoying nature with my two dogs Newt and Simon, and running Dungeons & Dragons campaigns as a Game Master for my local game spot!
I’m thrilled to be part of a team that shares my love and commitment to animal welfare and look forward to helping your pets stay happy and healthy!
