Kristen, CVT, VTS (Cardiology), Specialty Services Supervisor

Kristen grew up attending summer camps and volunteering at the shelter at the MSPCA-Nevins Farm. Her passion for animals led her to attend Essex Agricultural and Technical High School (now known as Essex North Shore Agricultural and Technician High School).

She began working as a kennel attendant/veterinary technician in 2001 and obtained her veterinary technician certification in 2005. In 2005, Kristen started working for the MSPCA-Angell – Western NE in Springfield, MA. The closure of the hospital in 2007 led her to her next journey at Tufts University Cummings School of Veterinary Medicine, starting in the intensive care unit. From there, she joined the cardiology department, became a Veterinary Technician Specialist in cardiology, and then moved into a leadership role as Supervisor for various Specialty Services at Angell West in 2022.

Her professional interests include providing the best patient care to our patients and clients, teaching and providing technicians and assistants the necessary knowledge and skills to succeed, and of course, anything cardiology.

Outside of work, she loves spending time with friends, exploring different food and drinks, and finding entertainment in the playful antics of her cats, Link and Leo.
