BioSphere Testimonials

"I hired a septic consultant who was highly recommended, and after two years of frustration and a lack of responsiveness I ended up with a plan that I could not use. So I hired Andrew Brownstone, and in less than 5 weeks he designed a far superior septic system that would work for my project, cost less to install, AND he had it approved by the Santa Cruz County Environmental Health Department. It is fantastic to work with someone as professional and capable as Andrew. I give BioSphere Consulting, Inc. my wholehearted endorsement!"

– Suzanne Holmes, Home owner in Boulder Creek, CA

"My neighborhood doesn't have city sewers, and due to the slope of my yard and neighboring properties, my septic field would fail during significant rains. I had two other guys work with me on the issue over an 18 month period, and I spent thousands re-doing my septic field, all without results. Frustrated, I did a lot of research, and came across Andrew, who came highly recommended from several reliable sources. Andrew was professional, personable and he was on time and knew his field. He diagnosed the problem and recommended a home treatment system. He designed the system, got the paperwork done, and oversaw the installation. He was always on time, and kept me informed throughout the process. The system has been in place for two years, and it works perfectly. He is among the best service providers I've worked with in Santa Cruz, and I would recommend BioSphere Consulting to others without hesitation."

"Compared to my first painful experience 'trying' to get an alternative system designed and permitted, my experience with BioSphere Consulting was ten times more professional. Everything went quite smoothly."

– Rick Gregg; Home owner in Boulder Creek, CA

"Andrew has mastered the skill of blending technical issues, project management and client relationships. He is the rare consultant that is able to clearly define his scope of services and complete them within the stipulated time frame. His outstanding reputation at designing waste water treatment systems precedes him at most local jurisdictions, making his submittals and the consulting leg work all the more effective. Andrew is your man if you need to hire someone that integrates well with the design team concept and understands "on time on budget."
