Dear Patients and Friends,

Thanks for choosing me to support you in your personal health goals! I’m a California native, originally from Huntington Beach. Before Mount Shasta I lived in Glacier, Washington; Ashland, Oregon; and Durango, Colorado, where I completed my undergraduate education.

Prior to medical school at Bastyr University in Seattle, Washington, I worked for a natural foods and supplements retailer, for an outdoor retailer, and as a whitewater river guide on the Rogue and Klamath rivers for many years.

I chose Mount Shasta to make my home and start my practice because I like living in a small mountain community and value outdoor recreation and healthy lifestyles.

You might see me, my husband Nick, and our two dogs outside skiing, hiking, climbing, rafting, surfing, or simply sitting on the porch and taking it all in. My priorities are a meaningful and quality life filled with love, laughter and joy.



Dr. Caselli set up her private practice in Mount Shasta, CA in 2014.

Dr. Caselli completed medical school at the renowned Bastyr University. The curriculum is similar to that of an MD or DO, with conventional diagnostics and disease management, in addition to complementary & alternative medicine.

Dr. Caselli also completed two years of clinical rotations at the Bastyr Center for Natural Health as well as specialty rotations off site, including Diabetes and Cardiovascular Disease Wellness, Dermatology, Pediatrics, Mental Health, and Public High School shifts.

"I am active woman in my early sixties who began experiencing a lack of energy, along with anxiety issues and cognitive impairment. Dr. Caselli reviewed my medical history and immediately recognized an underlying medical condition that turned out to be the cause of many of my symptoms. She recommended a few excellent (and affordable) supplements that support my vegetarian diet & overall health. Food allergies being an issue, she did further evaluation by using an ‘elimination diet’ process, which proved to be very effective for me. She is quick to identify underlying causes of many issues that aging women suffer from, and that I just assumed ‘incorrectly’ was just part of the ‘aging process’. My high energy level has returned and I feel happier and more focused and confident, as ever! Dr. Caselli is a wonderful communicator and very knowledgeable in the area of personal nutrition and how it relates to existing medical conditions. She is excellent in the areas of autoimmune deficiencies, digestive disorders and all the ways to rid your body of inflammation, to move onto feeling better!! She is a perfect partner for any woman to develop a personal health plan."

S.G., Dunsmuir, CA

"It was fantastic to have a doctor that really listened and viewed me and my concerns in an holistic manner. She asked important questions, and addressed my concerns with recommendations that would work for me; not cookie cutter answers. I highly recommend her."
