Hubbard-Hall Appoints Aaron Mambrino Appointed COO/Executive Vice President

Hubbard-Hall appointed Aaron Mambrino as Chief Operating Officer and Executive Vice President of the company.

Mambrino, a 20-year industry veteran, takes over from Gerry Mastropietro, who will retire after 41 years with the company at the end of 2024.

Mambrino joined Hubbard-Hall one year ago as Chief Financial Officer, leading the finance team and adding supply chain and customer experience to her responsibilities in June. As COO, she will be directly responsible for all company operations, including the company’s headquarters in Waterbury, Connecticut, and branches in Inman, South Carolina; Wilmington, Massachusetts; and Whitmore Lake, Michigan.

Previously, Mambrino served as the COO of Dymax Corporation, a specialty chemical manufacturer with over 400 employees and nine global locations. The company grew over 400% during her time there and expanded into several countries. She held various positions over her 20 years with the company, including CFO, President of Americas, and Global COO.

"I am thrilled to assume this role at a pivotal time in the company’s trajectory,” Mambrino says. “We have completed two successful acquisitions in the last 12 months and have an ambitious plan to streamline our distribution and manufacturing operations. With the exceptional team of customer-focused individuals at Hubbard-Hall, I’m energized and look forward to our future.”

Mambrino received a Bachelor of Science in accounting from Post University and a Master of Business Administration from the University of Hartford. Active in the community, she serves on the boards of Hartford Healthcare NW Region, Torrington Savings Bank, and Torrington Savings Bank Foundation. 

“Aaron is definitely someone you want in the foxhole with you,” says Molly Kellogg, Chief Executive Officer and President of Hubbard-Hall. “She is respected in the community and has a deserved reputation for professionalism, drive, and leadership. In her short time at Hubbard-Hall, she’s had an outsized impact.”

Kellogg says he is “beyond grateful” for Mastropietro’s years of service at Hubbard-Hall.

“I am thrilled that he will serve as Chief of Capital Projects and Compliance through 2024,” she says. “Nobody knows our company better, and his experience will help us calibrate for the future.”
