PORT JEFFERSON STATION, NY, August 11, 2026 /24-7PressRelease/ -- Mark Beukelaer, MBA, has been selected for inclusion in Marquis Who's Who. As in all Marquis Who's Who biographical volumes, individuals profiled are selected on the basis of current reference value. Factors such as position, noteworthy accomplishments, visibility, and prominence in a field are all taken into account during the selection process.
Mr. Beukelaer currently serves as a senior consulting associate on the forensic litigation and valuation services team at Grassi Advisory Group in Jericho, New York, a position he has held since 2023. In this capacity, he has distinguished himself as an expert in forensic litigation, earning recognition for his keen analytical skills and attention to detail. Among his most notable achievements, Mr. Beukelaer identified a 4 percent overcharge on general conditions during a construction monitoring project, successfully arguing that the charge was already covered under the insurance agreement. This discovery resulted in the recovery of several million dollars for the client. Additionally, he was engaged to investigate tax reporting practices for a group of restaurants, where his findings led to the recovery of $1.8 million in underreported taxes.
From 2021 to 2023, Mr. Beukelaer served as a semi-senior consulting associate at Grassi Advisory Group, further developing his expertise in forensic analysis and financial management. His earlier professional experience includes working as a summer camp counselor at Long Island Child Care Services in Coram, New York, from 2015 to 2020, where he contributed to youth development and community engagement. In 2018, he was a summer management trainee intern with Enterprise Holdings in Centereach, New York, gaining valuable insights into business operations and customer service.
Mr. Beukelaer's career also includes serving as an intern at TruNeed from 2017 to 2018, where he honed his research and organizational skills. Earlier still, from 2014 to 2018, he was a sales associate at Abercrombie & Fitch, where he developed foundational skills in sales and customer relations. Throughout his professional journey, Mr. Beukelaer has been an active member of Alpha Sigma Phi-Epsilon Nu Chapter, reflecting his commitment to professional development and industry engagement.
Mr. Beukelaer's academic background has played a significant role in shaping his career achievements. He earned a Master of Business Administration with concentrations in Business Analytics and Supply Chain Management from the Binghamton University School of Management in 2020. He completed a Bachelor of Science in Financial Economics at Binghamton University in 2019. The rigorous training received through these programs provided him with the analytical tools necessary for success in forensic litigation and valuation services. He credits his upbringing for instilling the values that have guided his professional path; his parents' emphasis on hard work and self-reliance remains central to his approach. Teachers and family alike encouraged him to focus on one issue at a time — a strategy that continues to inform his problem-solving methods.
Beyond his professional responsibilities, Mr. Beukelaer has demonstrated a longstanding commitment to civic involvement through volunteer service with several organizations. He has participated in Grassi Gives Back Day, Grassi's volunteer initiative program, almost every year of his career with them from 2021 to 2026. From 2015 to 2017, he volunteered with the Binghamton Salvation Army, contributing to community support initiatives. He also volunteered at Ultimate Taekwondo Center from 2011 to 2014 and with Long Island Child Care Services from 2011 to 2013, reflecting a dedication to giving back and supporting youth programs.
Born on Long Island, Mr. Beukelaer married Christina in July 2026. Outside of work, he enjoys watching sports and movies as well as bowling. Looking ahead, Mr. Beukelaer aims to advance within the forensic litigation team at Grassi Advisory Group and ultimately become recognized as the go-to expert for forensic litigation and valuation services — someone whom colleagues trust for guidance and clients seek out for effective solutions.
