Peninsula Tanks, Inc.

Peninsula Tanks has been in business since 1971. Rocky became manager in 2003 and bought the business from the original owner in 2017. His business philosophy to create friendships with both homeowners and commercial contractors is reflected in his loyal customer base. He and his employees strive for service with a smile, taking care of all of their customers with the same great service, from the smallest to the largest. They also do what they can to be environmentally friendly, using biodegradable form oil and also repurposing the excess concrete by sending it out to be re-ground and used again.

In his spare time Rocky enjoys horseback riding and watching his kids team rope and barrel race in rodeos around the state. He supports local youth sports and rodeo.
