Daniel Leavitt, MD
Joined Lassen Medical Clinic:
- 2021
Education:
- Bachelor of Science, combined Physiology/Biochemistry Major, University of Alberta, 1993
- MD Degree, University of Alberta, 1997
- Family Medicine Residency, University of Calgary, 1999
I am married and have a large family with 8 children, 9 grandchildren and counting. The grand children come much more quickly than the children did. Family has always been my focus and I strive to care for my patients as if they were my family. After completing residency training I had the opportunity to take over a solo practice on a small island in western Canada. I was there for 11 years providing cradle to grave traditional family medicine. Our family took a 7 month sabbatical and did a humanitarian medical mission in Vanuatu. The last 10 years I have focused exclusively on Emergency Room work providing services in a rural location. I am excited for our families’ new adventure in beautiful northern California.

Minh T. Nguyen, DO
I was born and raised in Vietnam. I came to the USA and went to UC Davis for my undergraduate. I met my husband in medical school in Mesa, Arizona and we finished residency together in Pennsylvania. I have done a few mission trips where I became interested in medicine. I enjoyed helping the people in need and I felt that improving one’s well-being and overall health is one of the most important ways to help others and give back to the community. I am interested in Osteopathic medicine, preventative care, women’s health, and office procedures. I want the best for my patients; I will work hard to provide the best care, as I would for my own family. I also hope to participate in more mission trips in the future.
I enjoy spending time with my family, hiking, traveling, baking and cooking. I also take great joy in home renovations and other DIY projects with my husband.
