It was there I met my high school sweetheart, now my husband of 20 years. We relocated to Alabama for my husband’s job and over the years had three beautiful children. We decided to make the shift to Montana to allow a slower, more adventurous pace for our younger children to grow up in. I enjoy spending time doing nearly anything outdoors with my family and especially love horseback riding. Prior to nursing, I trained young horses as well as dealt with horses with behavioral issues.
