The Team

Mike Randall

With the formation of Signature Pools Ltd., Mike has realized his goal to create the premier design and build firm. It is the standard-bearer in all facets of performance in connection with concrete pool design, construction, landscaping and service. A pool industry veteran of more than 30 years, he has always brought passion and perspective to the numerous outstanding projects he has collaborated on with his new partner Jim Vossen. As a forward thinker, Mike is privileged to combine all of these superb collective talents to form one great company, Signature Pools Ltd.

Jim Vossen

A pool builder for more than 40 years, Jim takes the same zealous pride today as he did those early days of pool construction. He is a hands-on craftsman and has a direct approach to engineering, organizing, and managing custom concrete pool installations. Jim brings a wealth of engineering knowledge and invaluable practical application principles to Signature’s production team. His ability to diagnose situations and correctly craft the necessary solutions is another key piece to ensure that Signature Pools Ltd., remains the industry leader in concrete pool construction.

Eric Granheim

Customer service is Eric’s utmost priority. This focus allows our company to bring professional service to your door step from start to finish of construction and the subsequent yearly service. He has been personally responsible for the service operation of Randall Pool and Spa for nearly 20 years. His Norwegian work ethic is beyond reproach. The logistics and scheduling of crews is an ongoing process that is monitored daily by Eric to ensure that our clientele receives our unsurpassed Signature Pools Ltd., Concierge Service to which they have been accustomed.
