Mike Treinen
To all of my faithful clients — it has been a privilege to serve you over the last 25 years. Thank you for the trust you placed in my work. As I turned 80 recently, I felt it was time to retire from doing field inspections and begin a new chapter. I will miss the personal connections I had with all of you but hope that I see you or hear from you somewhere around our beautiful county. Feel free to call with questions or discuss jobs we have already done.
So as to not leave you without septic system related assistance, I am providing referrals to two levels of service providers — all of whom have agreed to be listed below. Feel welcome to let any of them know that I referred you.
