Who We Are

Q: Why Delap? A: It’s the people.

When Virgil DeLap founded our firm in 1933, he set out to build a company focused on delivering exceptional accounting services to clients, as well as a firm where employees could pursue their career aspirations in public accounting while leading a balanced life.

Throughout the decades, our firm has grown, but we have never wavered from a pursuit of excellence. We have stayed true to the belief that quality client service begins with genuine care for people.

Delap consistently receives the highest marks during peer reviews performed by outside CPA firms — a glowing example of our firm’s continued commitment to excellence in all areas of our practice.

Our low staff attrition gives us a distinct competitive advantage over other firms. Our clients consistently praise our ability to return the same client service professionals to their accounts year after year.

The Road Ahead

We’re a fully integrated financial services firm with experts in tax, assurance, business advisory, wealth advisory, and cybersecurity. Our team consists of talented professionals that guide businesses at every stage. We’re blazing a new trail and giving clients a comprehensive view of their financial picture — then helping them protect what they’ve built.

In 1933, Virgil DeLap left a successful national CPA firm to start a new Oregon accounting firm that better matched the culture and values he believed made companies better.

Virgil handed his role as Managing Partner to his son, Vern, who passed the baton to Jim White. After more than 20 years as Managing Partner, Jim passed the role to Virgil’s grandson Dave DeLap.

In 2009, Delap welcomed the clients and people of Symonds, Evans & Company to the existing practice. The merger brought the addition of two audit partners and a wealth of resources. With the combined forces, Delap now has over 100 team members.

In 2015, former third-generation Managing Partner Dave DeLap passed leadership of the firm to Alex Corrigan — an assurance partner with more than 25 years of public accounting experience.

Most recently, Alex Corrigan passed the role of CEO to Earl Pierce, a proven leader with business vision who has been a tax partner with the firm for 15 years.
