Owner and Chief of Staff

Hi, I’m Dr. Dewey. Once I realized that every animal I interact with ended up stealing a piece of my heart, I decided that a career advocating for animal health was the right profession for me. Instead of following in my family’s footsteps entering the movie industry, I embarked on a journey to become a veterinarian.

I was very lucky to have found my passion at such a young age, because it allowed me to get a head start on my education. While in high school I also attended night classes at College of the Canyons, so by the age of 17, I had graduated from high school and obtained my associate degree in Biology, making me one of their youngest college graduates. I then attended California Polytechnic University, Pomona where I received by Bachelor’s degree in Animal Sciences. To satisfy my desire to understand the prevention and control of diseases between animal and human populations, I obtained a Master’s degree in public health at the University of Southern Mississippi where i worked along epidemiologist during the H1N1 outbreak.

I continued my training at Western University of Health Sciences in Pomona, CA where i  received my doctorate degree. During my 4-year journey through veterinary school, I was the NAVC (North America Veterinary Community) representative, as well as the president of the Student Chapter of Christian Veterinary Missions. I was elected to serve as a USA delegate at the International Symposium on Wildlife Utilization in South Africa, where I worked with various wildlife species, including elephants, giraffes, zebras, rhinos and large cats. I then completed an extensive 1-year internship in small animal internal medicine and surgery at Southern California Veterinary Specialty Hospital in Irvine, CA.

I served for 6 years on the IACUC committee at Biola University, lead a large team of  doctors at a progressive small animal practice in Orange County, CA and worked at multiple specialty hospitals where i further advanced my endoscopy and surgical skills.

I love working in a field that is continually evolving and I believe it’s important to stay up to date on current diagnostic and treatment modalities. I completed additional training and achieved certificates in regenerative stem cell therapy, veterinary acupuncture, advanced soft tissue surgery, endoscopy and advanced ultrasonography. I have also received recognition as a Certified Fear Free Professional and a Cat Friendly Professional.

Through creating Treehouse Animal Hospital, my hope is to not just provide top-notch veterinary care; but to build a community where pets and their families feel seen, heard, and cared for. Come join me in this journey of compassion and well-being!
