Their son, Doug, joined the company in 1967 and started the septic cleaning and portable toilet rentals division of the company.  In 1977, a home building division was started and over 800 homes were constructed.  Then, in 1979, the HVAC department was added with Doug at the helm of its operations. In 1981, Doug was made President and he immediately began to expand the company with nine acquisitions in three states.  He sold off the home and HVAC divisions in order to build and focus entirely on the portable restroom business. Today, Doug Pierson and his staff continue to strive to exceed customer expectations in their service to them. Index Contact Us!
