Leadership Team

Meet the team behind GD Barri’s success!

Executive Leadership

Alexandria (Alex) Dorsey


Ms. Alexandria Dorsey began as CFO from startup and assumed ownership of GD Barri in 2018 after the unexpected passing of Barri's founder, Georgia D. Barri. Since assuming leadership, Ms. Dorsey has strived to continue Georgia’s path and legacy to keep Barri on the forefront of contract services, which is now a Minority Woman Owned Business Enterprise.

Prior to joining GD Barri, Alex worked with Georgia for eighteen months for a west coast contract engineering firm. Before that her experience includes eight years with a major Nuclear Utility in the Northeast, where she advanced from Accounting Clerk to Assistant Manager of Accounts Payable responsible for monitoring contracts with large A&E and Construction/Maintenance firms. Transference of the skills gained with the utility to the contract technical services industry makes her exceedingly sensitive to our client’s needs, with deep understanding of recruiting, client maintenance, financial and legal issues, procedure development, marketing and more. Her unique experiences and knowledge allow GD Barri to continue as a leader in contract technical services.

When there is such a thing as “spare time”, Alex enjoys sewing, DIY home improvement, cooking and staying sharply competitive with family game night and sudoku challenges.

Rick Duff

Senior Consultant

Mr. Duff’s professional career began in 1977 at Enrico Fermi II during construction of that facility. Since then, he has worked within the nuclear power industry in the areas of procurement, contract administration, and program management at over a dozen nuclear facilities. His involvement with supplemental labor spans over four decades while working directly for a national construction company, two nuclear utilities, two consulting companies, and finally, with GD Barri, since 1990. His unique perspective comes from working for both client and vendor organizations, working in union and non-union environments, and working in over forty states. His broad experience includes one-of-a-kind labor agreements and contracts that have altered the way supplemental labor is provided to clients experiencing economic and political pressures.

Rick currently serves as Senior Management Advisor, which means he is very much involved with Barri’s Executive and Senior Team, but he is no longer directing programs on a day-to-day basis. The last thirty-plus years with Barri has been rewarding, stressful and, most of all, interesting. His philosophy has been: “There are no shortcuts or magic systems, there is only hard work and perseverance”. He is proud to hand the reigns over to such a talented group of professionals.

Jeff Wenger


Jeff Wenger is responsible for all the company’s financial functions, including accounting, audit, treasury, and corporate finance. His career at GD Barri spans more than 28 years and has experience in financial management, business leadership and corporate strategy.

Prior to being named CFO in 2018, he played a key role in developing and implementing polices that have led to the company’s longevity and accomplishments. He is thrilled to be intricately involved in the company’s success and connecting with deserving job seekers and employers across the country.

Jeff enjoys traveling with his wife, cooking, and participating in marathons. Mr. Wenger earned a Bachelor of Science in Business Administration and Accounting degree from Bowling Green State University.
