Meet the Team

  • Dr. Thomi
    Dr. Lucas Thomi D.V.M

    Dr. Thomi was born in Switzerland and spent most of his childhood near Basel.  After graduating from technical school, obligatory military service and working as a machinist for one year, he continued his education first in England and then New York State. When the opportunity arose to work at a rural school in the Dominican Republic, he moved there without hesitation.   Dr. Thomi ultimately spent over four years working and living in an isolated community, called Rio Limpio, located in the central mountain range in the Dominican Republic near the Haitian border.  After leaving the Dominican Republic he first moved to Maryland and then to Colorado to complete his Bachelor of Science degree in agronomy followed a doctorate in veterinary medicine at Colorado State University.

    Shortly after graduating Dr. Thomi moved with his young family to Helena. For the first year after graduation he worked at the Animal Center and completed his acupuncture training at Colorado State University. In 2000 Dr. Barkemeyer, Dr. Fehlig and Dr. Thomi opened the Companion Animal Hospital, a small and large animal hospital, on North Montana Avenue. The Companion Animal Hospital closed in 2010 after Dr.
    Barkemeyer had passed away. In December 2010 Dr. Thomi and most of his staff moved to the newly constructed Apex Animal Hospital, which was designed as a modern small animal internal medicine and surgical hospital with a state-of-the-art physical rehabilitation facility.  Dr. Thomi’s special interests are orthopedic and advanced soft tissue surgery, but he also enjoys
    challenging internal medicine cases.  Although Dr. Thomi mostly works on dogs and cats, he has performed surgery on animals as small as a 6 gram toad that had swallowed a rock, to a Grizzly bear with a fractured jaw.

    While Dr. Thomi strives to continuously improve his hospital and provide the best services possible for his patients and clients, he also loves to learn new skills in his free time and challenges himself physically and mentally.  Hobbies include bee keeping, raising sheep and sheep herding with his dogs, SCUBA diving, sailing, standup paddle boarding, wood carving, fishing and hiking.

    bring canine rehab to Montana? After developing a working relationship with both PT and DVM state boards she completed her CCRP in 2004. And then went on to pioneer a path for canine rehab in Montana that brings out the best of both PT and DVM for each canine
