Brandon Mauck, Co-Owner (Westfall Septic)

As the fourth generation of his family in the septic service industry, Brandon understands the importance of getting the job done right the first time and setting a higher standard than the competition. Westfall Septic has provided timely, effective solutions to the most challenging septic tank problems – and that’s Brandon’s favorite thing about his business.

Jeffrey Phelps, Co-Owner (Westfall Septic)

Jeff started out working on a septic pumping truck in 1990, and went on to operate a septic installation company before joining Westfall Septic in 2014. Working alongside Dan Bush (Oregon’s “guru of septic tank systems”), Jeff learned the ins and outs of even the largest, most complex systems. His focus is on reducing homeowner stress by designing septic systems for long-term function, installing quality products, and respecting people’s property like it’s his own.

Jeff studied mechanical engineering at Oregon State University, and is a licensed installer and maintenance provider. In his spare time, he enjoys working on his hobby farm, spending time outdoors and being a private pilot.

Jeremy is detail driven and always makes sure everything is done to the best of his ability. Jeremy is an Army veteran, an avid sports guy, and an outdoorsman. He's a hard worker and family man. Outside of work he is a proud father with a newborn.
