After an extraordinary 35-year career with The Wilkinson Companies, we announce the 
upcoming retirement of Al Bishop, our Vice President of Sales, effective May 30th. Al has been an invaluable part of our journey, dedicating three and a half decades to building, leading, and inspiring the sales organization. From forging lasting relationships with associates, customers and partners, Al’s legacy is woven into the very fabric of Wilkinson Companies.
“The team approach here at GTW is evident and is proof positive of our collective ability to develop and sustain our client base over the past 35 years, which I am proud to have been a part of. I am grateful to the team, including all areas of the company, and the support they provide.” – Al Bishop
As Al begins his retirement, John Sieminski will step into the Vice President of Sales role. John has been with The Wilkinson Companies for 38 years, most recently as Vice
President of Service Operations.
“Not only is John the ultimate team player, but he already has partnerships with most of our clients, and he is more than up for a new challenge! We expect this transition to go very smoothly and know that John will thrive in this role.” – Geoff Wilkinson, Jr.
In addition, we have hired Danny Riley as a Sales Engineer. Danny, who rejoined us on January 20th, previously worked in the Service Department with 
John as Assistant Service Manager as well as a Service Technician and took a new opportunity a few years back.
“I always enjoyed interacting with our customers and ensuring that they were satisfied with their boiler room needs. Now, to be able to work with our customers in a different way and have a direct impact on making a difference to improve their boiler plant operations, I couldn’t be happier. I’m really looking forward to my future with The Wilkinson Companies as a Sales Engineer and building many more relationships.” - Danny Riley
Finally, Service Technician Mike Grinham has been promoted to Service Manager effective March 2025. Mike has been with Wilkinson for 7 years. He has a well-rounded
background not only technically but also has strong organizational skill sets.
"Mike is a man of integrity and hard work and we are more than confident that he will lead the group into a bright future!" - Geoff Wilkinson, Jr.
As The Wilkinson Companies continues to evolve, these key transitions reflect our commitment to investing in people and building a strong, forward-looking team. We are deeply grateful for Al Bishop’s decades of leadership and dedication, and we look forward to the continued success of John, Danny, and Mike in their new roles. With a strong foundation and a clear vision for the future, we are excited for what’s ahead and confident that our team will continue to deliver the excellence our customers have come to expect.
