  • Dr. Trish Roisum, DVM

    Dr. Trish started her career as a veterinarian working with companion animals, farm animals, and wildlife in a James Herriot-esque practice in rural southern Oregon. She cherishes those small town memories, the incredible adventures, and life altering experiences that laid the foundation for the veterinarian she is today. Her second position was in a busy small animal hospital in Olympia, Washington which was a period of incredible growth. She obtained her Veterinary Spinal Manipulation Therapist certification, allowing her to incorporate chiropractic care into her practice regime and started her path into complimentary medicine. This was followed by acupuncture training and integrating that modality into her practice offerings. She is excited to start homeopathy training late in 2015.

    Now Dr. Trish is grateful to be able to practice alongside Dr. Penny Jacobs and Dr. Jess Cameron. She appreciates  their similar beliefs in a strong western medicine background beautifully meshed with holistic practices including nutrition, acupuncture, herbs and supplements. She truly appreciates Berry Hill's friendly environment, caring staff, and fantastic clientele.

    As a veterinarian, she loves discovering the best opportunity for healing and support in each situation. Dr. Trish appreciates, respects, honors, and celebrates the human animal bond. Providing hospice care and helping patients peacefully transition are important aspects of her practice. Her goal is to provide high quality veterinary care with clear communication in each situation.

    Dr. Trish'™s family includes: her lovely partner Lee, who is her motivation for her move to Portland, Lavinia the Siamese plus sized model, Bert the best "œBerter Collie" ever, Miss Qi Chihuahua a party in a dress, orange Oscar a perpetually surprised cat and Sylvia the feline matriarch sometimes known as Scrappy.

    When not at Berry Hill, Trish enjoys traveling to visit her friends and family in the mid-west. She loves gardening, a good yoga class, Vipassana meditation, cooking, reading and learning.

    Dr. Trish looks forward to meeting you and your family.
