Diana LJ Harrison started Diana LJ Harrison CPA, P.C. in 1992 after several years in public accounting.  While Diana thrived in a larger accounting group, she sought to build a practice that better match her vision and values. Her vision was simple – build an accounting practice that clients saw a true partner, not just in tax planning and preparation, but in building overall financial and health. Additionally, she wanted to surround herself with staff that was focused on individual development and dedication to their craft.

In 2012, Diana brought on her first partner and after twenty years a sole practitioner, changed the name to Lewis & Harrison CPA Group. Kelsey F. Lewis, CPA joined the practice in 2011 after working closely with the firm for many years as a seasonal tax preparer.  The addition of Kelsey as partner ushered in a new generation of CPAs, which will allow the firm to continue to grow and serve our clients for many years to come.

At Lewis & Harrison CPA group, our breadth and depth of knowledge, combined with our staff committed to excellence, gives us a distinct advantage over other firms. We receive consistent feedback and praise from our customers on our ability to deliver high quality and high value year after year. By allowing our staff to focus their skills and invest in their continued development, we continue to raise the bar.  As our firm continues to grow, our commitment to delivering quality and value has only strengthened.

Now don’t just take our word for it. Our CPAs participate in regular peer review and quality controls programs required for membership in the AICPA and Oregon Society of Certified Public Accountants.  These reviews are performed by an independent CPA to provide an objective look at our quality of work. We continue to receive the highest ratings available. Their feedback strengthens our staff and continues to keep us on the forefront of delivering value.
