    I got my start in the medical field as a teenager—working with my mom at a radiology office and billing service. Over the past years I’ve gained extensive knowledge in all aspects of medical billing for multiple specialties. On a whim, my husband and I decided to move to California in 2001 from beautiful North Idaho. I’ve been happily working with the ACM team ever since. My husband and I have been married since 1996 and we have two amazing daughters, Margie and Milla.

  • Ashley


    I started in Chiropractic in 2003 as a C.A. & now specialize in insurance collections. Our industry is always changing & I love the challenges of the work we do. I am so happy to have found a home with the ACM family.

    In my personal time I love to spend our SoCal sunny weekends outdoors exploring our costal trails, listening to live music, or deep in a good book. I am a lover of dogs, public radio & really bad reality T.V.
