“Sheri is an accomplished operations executive with a strong record of leading complex organizations and building high-performing teams,” Merit Medical President and CEO Martha G. Aronson, said in a press release. “Her experience strengthening integrated business processes, ensuring product availability and driving global operational excellence will be important as Merit continues to scale globally and execute its long-term growth strategy.”
To support continuity, Neil Peterson will move into the role of senior advisor, where he will help ensure a smooth transition through March 5, 2027. At that time, Peterson will complete his service to Merit after more than 32 years with the company.
Peterson has held leadership roles across Merit’s operations and engineering functions, most recently serving as chief operating officer for the past four years. Throughout his career, he has strengthened product quality, improved on-time delivery, advanced operational efficiencies and driven cost reductions, the company said in a press release. He also helped navigate supply chain constraints, raw material shortages and the operational challenges of the COVID-19 pandemic.
“Neil has been a dedicated and respected leader at Merit. His operational discipline, commitment to execution and deep knowledge of our manufacturing and supply chain network have contributed meaningfully to the company’s growth and performance,” added Aronson. “We are grateful for his many contributions and for the important role he has played in strengthening our global operations.”
There have been several leadership changes at the company since Aronson was named president and CEO on Oct. 3, 2025. In 2025, John Hall became EVP of Global R&D, and Adam Smith was appointed as chief commercial officer. Pete Dankwerth joined Merit in May 2026 as EVP of Global Enterprise Excellence.
