CMC, the largest provider of integrated intermodal solutions in the U.S., today announced the retirement of Shawn Olshefski following 30 years with the company, concluding an extraordinary career defined by commitment, relationships and service to CMC’s customers and the broader maritime community.
Mr. Olshefski joined CMC, then known as Marine Repair Services/Container Maintenance Corporation, at the end of December 1996. Over the three decades that followed, he became an integral part of the company, building lasting relationships with customers, colleagues and industry partners while sharing his knowledge and experience with the people around him.
“Thirty years together creates a bond that goes well beyond the workplace,” said Vincent J. Marino, CEO of CMC. “Shawn has been part of our family since the day he started, and that relationship has only grown stronger over the years. We are incredibly grateful for all he has contributed, but even more so for his loyalty and friendship. We will miss having him with us every day, but we couldn’t be happier for Shawn as he begins this well-deserved next chapter. He will always be part of the CMC family.”
Mr. Olshefski’s retirement also comes as he marks 40 years working at the Port of Baltimore, having begun his maritime and transportation career there in June 1986.
His commitment to Baltimore’s maritime community extends well beyond his work at CMC and the port. Mr. Olshefski has served for 29 years on the Steamship Trade Association of Baltimore Board, previously served as a Trustee for I.L.A. Pension & Benefits in Baltimore, and has been a longtime member of the Propeller Club of Baltimore and the Maryland Motor Truck Association.
One of the most meaningful chapters of his CMC career has been the opportunity to spend the past 10 years working alongside his daughter, Samantha Olshefski, sharing his experience and helping guide and mentor her as she builds her own career in the industry.
The connection between family and career is particularly fitting for Mr. Olshefski, who often jokes that three of the best things in his life happened in 1996: the Cleveland Browns moved to Baltimore and became the Ravens; Samantha was born in September; and he joined Marine Repair Services/Container Maintenance Corporation at the end of December.
As Mr. Olshefski prepares to retire after 30 years with CMC, he leaves a legacy that extends well beyond his accomplishments. It can be seen in the relationships he has built, the people he has mentored and the knowledge he has shared with the next generation. While his daily presence at CMC will be greatly missed, the impact he has made on the company and its people will remain for years to come.
