Hello! I have my ASW and previously practiced in West Jordan, UT. I have experience in providing mental health counseling in residential treatment centers for adults and adolescents servicing a variety of mental health concerns.  I provided individual, family, and group services for adolescents with behavioral, substance, and mental health issues primarily focused on reuniting and strengthening the family system.  I serviced adults in residential treatment for substance use and mental health concerns providing individual and group therapy.  Outside of work, I enjoy spending time outside hiking, rock climbing and searching for new places to explore.

I was born and raised in Lassen County and have worked with the public at IGA, Ace Hardware, and as a teacher assistant for McKinley’s afterschool program. I have also served on P-CREW for the Fire and Ranger Station. I attended Lassen High School and  Lassen College majoring in Business. I attended a service mission to help others in Idaho and Utah for 15 months. I love setting goals and achieving them. Helping others is the most important thing I do, as  well as learning from other people. My hobbies are puzzles, putting things together, making friends, playing games, reading, swimming, watching movies, and going on walks.
