  • Dr. Penny Jacobs – DVM

    Doctor

    Dr. Penny Jacobs graduated from the University of Georgia College of Veterinary Medicine in 2001. She started her veterinary career in Athens, GA and then decided to move to the great Northwest in 2007. She helped re-launch Berry Hill Veterinary Center in 2008 and completed the International Veterinary Acupuncture Society (IVAS) course in acupuncture soon after. This opened her eyes up to the world of alternative and complementary medicine which she has integrated into her already holistic approach. Dr. Jacobs further developed her holistic education and practice by studying Food Therapy at the Chi Institute and incorporates this nutrition knowledge as well as Chinese herbs and supplements into her daily practice. She also performs surgery and other modalities of traditional medicine like dentistry, diagnostics, and vaccines and her holistic medical education influences those practices as well. When she is not working she enjoys spending time with her husband, friends, Irish Wolfhound and her kitties, hiking, biking, skiing and cooking.

  • Dr. Trish Roisum – DVM

    Doctor

    I am very grateful to practice alongside the wonderful healers at Berry Hill Veterinary Center. We are blessed with an amazing team that includes four veterinarians, three licensed veterinary nurse technicians, enthusiastic veterinary assistants and charming yet efficient receptionists.
    My career quite possibly began when at age 4, I asked my mom if I could go to college to become a bird. A few decades later, I graduated from the University of Minnesota College of Veterinary Medicine. My adventures as a veterinarian started in rural southern Oregon making small town memories. Large animals, companion animals and wildlife were teachers and guides. I cherish those incredible adventures, life altering experiences and foundational lessons.
    My focus has narrowed through the years and my practice is now devoted to our canine and feline companions. I enjoy providing dental care, managing chronic health concerns and facilitating holistic wellness care with customized vaccination protocols. In addition to western medicine, additional training allows me to offer complimentary therapies such as acupuncture, veterinary spinal manipulation therapy, homeopathy, palliative care and hospice care.
    I cherish each puppy visit as much as I honor each end of life transition. I celebrate and respect the bond we form with our four legged family members. They share our lives for a variety of reasons: to support us, teach us, console us, guide us, love us, make us laugh, and to help us appreciate the little things.
    My goals as a healer and practitioner are to provide high quality veterinary care with clear communication tailored to each situation.
    When I am not practicing at Berry Hill you might find me gardening, hiking, reading, meditating, dancing, volunteering, or exploring the beautiful world we live in. My sweet husband Lee and I currently share our home with Miss Qi (card carrying chihuahua in a dress), Sylvia (our matriarch grey tabby), Oscar (perpetually surprised orange tabby), and Lavinia (Siamese, full of love).
    I look forward to meeting you and your family. In gratitude, Dr. Trish

  • Dr. Eva Denka – DVM

    Doctor

    Eva Denka is the newest doctor here at Berry Hill Veterinary Center. For as long as she can remember, Eva has wanted to practice veterinary medicine, without a doubt. She was surrounded by animals growing up on a farm with cows, horses, goats and chickens. As a child, one incident left quite an impression on her; her family’s dog was kicked by a horse and required emergency surgery. Eva did a school project on the dramatic episode and came away with a deep appreciation for the power of good medicine.

    Eva comes to Berry Hill after having graduated from the University of Washington with a Doctorate in Veterinary Medicine. She takes a personal approach to her practice by making meaningful connections with her patients and their families. She loves to watch her patients grow and thrive, while also tending to them during times of injury or illness. Eva is passionate about the power of preventative medicine, emphasizing healthy lifestyle choices for our fur friends. She takes a multi-modal approach which includes a balanced diet, regular exercise, and the implementation of both western and eastern medicine modalities.

    At Berry Hill, Eva deeply appreciates the quality of medicine that is provided to our patients due to our highly positive and collaborative staff environment. She loves the well-rounded approach provided by a team that is trained in modern and holistic medicine. Maintenance of a good work/life balance is a priority of Eva’s, allowing her to stay present within and dedicated to her practice of medicine. When she is not hard at work, she teaches fitness classes and is aspiring to complete yoga teacher training. She thrives on nature and travel, and loves to hike and camp with her dog, Porter, and her cat (yes, cat), Fuzz.
