History Prior to Becoming CEO

After growing up in Longview, Washington and playing high school football, basketball, and baseball, David decided to attend WSU to study a combination of Business and Information Technology. After college, David joined a CPA firm specializing in accounting for non-profits where for 4 years he did tax accounting and performed audits for non profits including United Way and Columbia Wellness. Seeking exposure to the business sector, he joined a privately owned large lumber company that owned and operated 16 saw mills in California and Washington. For over 2 years as the Sole Accountant in their Centralia, WA mill, he practiced managerial accounting, prepared financial statements, and performed cost accounting. 

In Nov 2009, David joined Columbia Wellness as CFO and 2 years later also became our COO to lead all Operations. At the time, Columbia Wellness was a substantially smaller organization than today. He quickly became a major force in allowing for subsequent growth by vastly improving finances and operations by implementing corrective actions to financial systems and practices resulting in our first clean audit and ensuring success of all subsequent audits to date;  Performing  a vital reconciliation with RSN allowing Columbia Wellness to recover $850K of previously unpaid Medicaid fees for services provided; Restructuring departments by hiring specialty employees to break up work and increase controls; Bringing in a Hospital Billing Specialist resulting in Columbia Wellness receiving $150K payment from Medicare for previously unpaid service; Moving our Child & Family Department to a larger facility accommodating over 30 employees; performing all IT functions including expanding and upgrading our suite of software, upgrading our computer network to increase its speed and allow flexibility for expansion, and overhauling our phone system to enhance organizational connectivity and customer service.
