RIVERS EDGE HISTORY

Rivers Edge Environmental has been a mainstay operation in the Puget Sound Area for over 20 years. In a jeep loaded down with only essentials, the Founder of Rivers Edge, Paul Kemp, moved to Washington from Kansas in the 1980s.

 

Through pure grit and determination, he forged a path in the remediation industry from the ground up. This company, and its commitment to quality projects and unmatched work ethic, has proven itself to be a force in the industry.

 

After working with Paul and his leadership for many years, Alex and Clayton Mullendore purchased Rivers Edge. With a plan to maintain the same quality of service that Rivers Edge is known for, Alex and Clayton work diligently to serve the needs of their clients while also being a responsible and trusted choice for their subcontractors and suppliers.

 

On a parallel road of growth and development, Alex and Clayton have added other services, such as asbestos, lead, and mold abatement, and the expansion of multi-state operations to increase impact and efficiency for their client’s projects.

WOMAN-OWNED

Alex originates from a family of entrepreneurs. Growing up, their family founded, grew, and sold multiple businesses. While always having a penchant for building and running companies with a background in entrepreneurship, watching the struggle of their family business through the 2008 recession pushed Alex to seek a more reliable career path that wasn't dependent on market conditions.

 

Graduating from Central Washington University with two degrees in Elementary Education, Alex's encounter with Paul Kemp in 2015 and working alongside him at Rivers Edge quickly made her realize that her skills could be put to good use there. Paul set his sights on retiring, and Alex set her sights on purchasing and expanding the business upon his retirement. The baton was passed in 2022 when Alex and Clayton Mullendore purchased Rivers Edge from Paul.

​

Alex envisions Rivers Edge as more than just a construction company; it's a place where employees feel valued and clients feel confident. She aims to exceed expectations, particularly on environmental projects, where winning bids isn't just about cost but about delivering exceptional results. Suppliers and subcontractors see Rivers Edge as a reliable partner, while clients can trust them to handle any environmental challenge with ease.
