In Memoriam: Scott Drennan – A Legacy of Dedication and Friendship

Scott Drennan
November 5, 1962 – August 7, 2023

It is with heavy hearts that we mourn the passing and honor the life of Scott Drennan, a remarkable individual whose impact reached far beyond his professional achievements. As the director of both gas turbine and aftertreatment applications at Convergent Science, Scott’s journey was one of dedication, innovation, and unwavering support for his colleagues, friends, and family.

Scott joined Convergent Science in 2012, when the company was aiming to branch out into gas turbine and aftertreatment modeling. In search of someone who would own and evolve our presence in these new markets, Scott emerged as a natural choice to lead our endeavors because of his renowned reputation in the field. Relocating his family from California to Texas demonstrated not only his dedication but also his willingness to embrace new challenges. Scott’s contributions to our gas turbine solutions were nothing short of transformative, a reflection of his ability to drive progress. 

Throughout his years at the helm of the Aftertreatment team, Scott exhibited an inspiring passion for growth. He masterfully guided the team’s evolution, from nurturing talent to crafting the very training program that paved the way for groundbreaking aftertreatment modeling with CONVERGE. Scott’s commitment to validation laid the cornerstone for client acquisition, future benchmarks, and software development. His oversight of key initiatives, such as urea deposit and filter modeling, was a testament to his visionary leadership.

Scott was more than just a professional. His love for live music, sports, and culinary experiences showcased his zest for life. His ability to find hidden gems in gastronomy enriched every journey. As a friend and colleague, he radiated warmth, leaving memories of shared laughter and camaraderie from countless trips and projects.

Above all, Scott’s conversations were frequently punctuated with stories of his greatest treasures: his wife, Julie, and his three children. His dedication to family radiated as he spoke with pride about his daughter’s accomplishments and his boys’ martial arts victories and educational achievements. Scott’s anecdotes and wisdom on parenting forged a bond, reminding us of the shared joys and challenges of fatherhood.

Scott’s legacy will forever remain a testament to the power of friendship, the pursuit of excellence, and the importance of cherishing those we hold dear. As we grieve this immeasurable loss, let us remember the light he brought to our lives and extend our deepest condolences to his beloved family. Though he is no longer with us, his spirit lives on in the memories we share and the values he instilled. Rest in peace, dear friend.
