We are proud to lift those around us via integrity, innovative thinking, and continuous improvement. Together, we build lasting relationships and a better future through teamwork, open communication, commitment and a spirit of service.

We Believe in Fostering Strong, Lasting Partnerships

Since our beginning in 1933, Geffen Mesher’s focus has been on supporting the lives, plans and goals of people – those we serve as well as those who call the firm home. We have a genuine concern for each client’s success. That’s a big reason why we seek to provide a full suite of professional business development services that include accounting and assurance, business consulting, estate planning, financial and retirement planning, litigation support, international services and taxation planning.

WHO WE SERVE

Geffen Mesher proactively provides financial statement audits, tax compliance and consulting services to privately held businesses, families and investors primarily in the Northwest.

Values Beyond Numbers

We know that the quality of our professional tax, assurance, financial consulting and reporting services affects the lives and financial well-being of those we serve. Therefore, we work from a core mission that points back to the people-side of the equation:

  1. Our mission is to help our clients achieve their goals.
  2. We proactively provide high quality consulting and compliance services to privately held businesses, families and investors primarily in the Pacific Northwest.
  3. We perform and deliver services with integrity and a sense of urgency.
  4. We give to our community by serving on boards of directors, making charitable donations, and volunteering our time.
  5. To accomplish this we hire and support motivated and resourceful people, and provide opportunities for them to lead successful personal and professional lives.

Our History

A graduate of City College of New York, Henry Blauer moved to Portland after serving in the Army during WWII. Soon after arriving, he met Ben Sussman, a CPA with a growing practice. In 1949, Ben and Henry formed the partnership Sussman & Blauer. Henry quickly became a trusted advisor to many clients, helping the business grow. In the 1960s, Henry hired two young accountants, Stan Geffen and Bob Mesher, both of whom became partners, and the firm was renamed Blauer, Geffen & Mesher. After merging with the national firm Laventhol & Horwath in 1970, the Portland office continued to serve clients until 1990, when Geffen Mesher was established as a single-office firm. In 2022, Geffen Mesher expanded its reach by acquiring a Vancouver office to further grow its business. Although Henry Blauer passed away in 2012 at the age of 91, both Stan Geffen (Shareholder) and Bob Mesher (Of Counsel) remain active in the firm today. Their years of hard work, commitment, experience, and expertise have been fundamental in building the firm’s solid foundation.

A History of Giving Back

The importance of giving back to the community is woven into the fabric of our firm, and is something we have been doing since our early days. Today, our professionals support more than 80 charitable organizations through serving on boards of directors, making charitable donations, and volunteering our time. In addition to our extensive organization involvement, we close our office for one day each year and volunteer directly in the community. Started in 2011, our annual service day is a remarkable way for us to not only strengthen the bonds of our employee relationships, but to have an impact on the communities we serve.
