Meet Our Team


  • Thomas Nickerson, DVM

    Dr. Nickerson received his BS from the University of Maryland and his DVM degree (with high honors) from the University of Georgia (Go Dawgs!).

    Following graduation from UGA, he spent a year as a pathology resident at UC Davis. During this time, he discovered that he preferred working with more lively patients. He left the residency program to pursue a more rewarding career in private practice.

    From 1979 to 1981, Dr. Nickerson worked as an associate veterinarian in Sacramento. He moved to Willow Creek in 1981 and spent the next 9 years in practice there. In 1990, he purchased Trinity Animal Hospital in Weaverville.

    Although the small building served him well for almost two decades, 2008 marked the opening of a long awaited modern facility on Ponderosa Lane.

    Dr. Nickerson shares his home with one good cat (Blackberry), one bad cat (Lilac), and The Kipper a fun loving border collie.

  • Mary Schlicting, DVM

    Dr. Schlicting received her DVM degree from Ross University, and completed her clinical year at Oregon State University (Go Beavers!).

    During veterinary school, she was involved with the feral cat 'trap and release' program, and served several semesters as the president of the student chapter of AAFP (American Association of Feline Practitioners). She also spent time assisting with sea turtle monitoring and nest preservation. In addition to her emphasis in feline medicine, Dr. Schlicting has a particular interest in llama, alpaca and goat medicine, as well as emergency and critical care.

    Dr. Schlicting was born and raised in Allentown, PA. She moved to California where she completed her BA at Mills College in Oakland. She moved to Trinity County to escape the city, and shares her home with 3 cats and 1 dog: Molly, Cido, Miette and Ophelia.

    When away from the hospital, Dr. Schlicting spends time trail running (with Ophelia), drawing, sculpting and backpacking.
