Dr. Mike Casemier

Dr. Casemier was born and raised in Grand Rapids, MI, and earned his undergraduate degree from Grand Valley State University after an honorable discharge from the U.S. Navy. He then went on to earn his veterinary degree from Michigan State University. He worked with horses early in his career but has since focused on companion cats and dogs. Dr. Casemier is grateful for the long-term relationships he develops with his clients. When he isn’t taking care of his patients, Dr. Casemier enjoys spending time with his nine-year-old chocolate lab named Dexter and his five-year-old, aptly named cat, Lilith.

Ashley – Veterinary Technician, CVT Practice Manager

My love of animals started very early in life. When I was born, my sister already had 8 horses. I grew up on a small gentleman’s farm in the Upper Valley of NH. By the time I was a young teen, we had 5 horses, pygmy goats, sheep, chickens, a steer: as well as several dogs, cats, rabbits, birds, and pet mice. I attended the University of Findlay for western equestrian studies, and then fell into the veterinary profession. I started as a veterinary assistant when I was 19 and continued to grow my veterinary knowledge. After working as a veterinary technician for 12 years, I became a certified veterinary technician in 2015. In 2018 I become the veterinary technician supervisor.

I live in southern NH with my husband, our 9-year-old son, Tanner; our 3-year-old pit bull, Loki, 4 chickens and a very old Chinese dwarf hamster. I enjoy almost any outside activity with my family; kayaking, fishing, hiking, biking, geocaching and just playing in nature.

Cristal started working as a Veterinary Technician in 1993.  She has worked in multiple Hospitals and Shelters in So. New Hampshire, for 30 years. Working with animals has been her dream since she was a child, and she cannot see herself doing anything else.  She has always wanted to make a difference somehow in animal lives.  She enjoys being an advocate for animals, treating all animals with kindness and respect always. The opportunity to be a comfort to animals and being their voice is most important. “They need someone to tell them its going to be OK, in the good times and at their worst.” Getting to know owners and Educating on animal care and behavior is also very important to her.

Marti – Lead Receptionist

Though she grew up in Queens, NY, Marti has called New Hampshire her home for a long time. She’s always loved animals and has worked in pet stores, volunteered in a wildlife rehab center, been a kennel attendant, and most recently has worked as a veterinary receptionist for about 6 years, the last 3 at Allenstown Animal Hospital. The most rewarding thing about working in the veterinary field, according to Marti, is being a part of a team of like-minded animal-loving co-workers and seeing the good that is done for pets of all kinds on a daily basis. When not at work Marti enjoys spending time with her husband Tim motorcycling around the state with Dolly – their 3-year-old Schweenie (Shih Tzu/, Dachshund mitt) every chance they get!
