I have been working for Centennial Mental Health since January 2009. I enjoy working with my co-workers and colleagues and with the diversity of clients as well. I previously worked as a school counselor in Craig, Colorado and moved to Benkelman, Nebraska in August 2008.

I enjoy learning from my life experiences including the people I meet and the variety of jobs I have had. I moved to Colorado from Michigan in January of 1996 for the ski season (that lasted 8 years). After working at a range of jobs from managing a t-shirt shop, working as a horse wrangler, raft guide and house mouse on a fish processing boat in Alaska I decided it was time to further my formal education. This is when I chose to attend the School of Education at Colorado State University.

My original goal was to focus on school counseling and as I became immersed in the program I realized that I had a draw to the community counseling aspect as well. This was when I decided to take the classes necessary for both school counseling and community counseling.

I am enjoying learning the cultures of rural areas on the high plains.
