Firm Partner, with KRP Since 1976

I knew as a young student that I wanted to work in a field where my math skills would be the central focus of my career. When I was a sophomore in college I decided the best fit for my career would be as an accountant. I’ve enjoyed that role ever since and am proud that I’ve been successful in working hard to become a partner with the firm.

The most rewarding part of my work has been my relationship with my clients. I feel like I’ve actually become a partner in their business because I serve as an advocate on their behalf to the government, to financial institutions and other entities with whom they do business.

I believe our staff at KRP works hard to fulfill the expectations of our clients and as a result, many of our clients have been with us for decades. And those clients have become friends beyond the business relationship due to the level of dedication and service we provide.
