Who We ARE
Silver Lining Adjustments opened in 2008 as an administrative services company focused on helping those experiencing troublesome interactions with insurance companies. In 2012, SLA relocated from Arizona to the beautiful Pacific Northwest where we began to focus on the plight of Alternative Care Providers. CAM Practitioners in private practice face a unique set of challenges when attempting to navigate the world of insurance. We believe that alternative medicine providers deserve trustworthy, diligent, and honest administrative professionals to support the valuable work they perform.
SLA provides effective processes which create a seamless, dependable procedure for accounts receivable management. We are always searching for the Silver Lining around the dark cloud of medical billing with consistent process refinement ensuring the most effective systems for our clients.
