Separately, the AMUG Board appointed Daniel Landgraf as Director of Sponsors & Exhibitors and Bruce LeMaster as Director at Large to fill vacated positions.

The results of the voting by AMUG Members, announced on March 13, 2024, during the annual AMUG business meeting, reflect a strong vote of confidence in the current leadership. VanDeren and Belson Barnes, who have proven their dedication and effectiveness, were re-elected to their positions for second terms. Bell, who has demonstrated his commitment and capabilities as Director of Sponsors & Exhibitors, will assume new responsibilities as Vice President.

Shannon VanDeren, current and incoming President, said, “We recognize the enormous commitment Gary has made to the AMUG community and are thankful for his dedication to our growth.”

Regarding the newly named AMUG Board, VanDeren said, “The board of directors that will serve AMUG for 2024-2025 is comprised of a variety of backgrounds, skillsets, AM disciplines, years in the industry, and personalities. Yet collectively, they are focused and committed to upholding the integrity and purpose of AMUG.”

She continued, “We will have the opportunity to glean from the diverse perspectives and viewpoints of our board members, consisting of men and women, U.S. and international citizens, engineers and non-engineers, as well as people with business-oriented and technically focused careers. I look forward to healthy conversation and a forward-moving approach!”

The multi-year terms for these positions will commence on July 1, 2024. The balance of the board includes three elected positions and one appointed position, each with one or more years remaining in their terms.
