Certified Wastewater Specialists

Friendly and Knowledgeable Staff

Prior to being allowed on any customer job site or dealing with any customer issue all of our technicians and office staff begin their careers at Fiedler’s with a minimum of three months of orientation to their job requirements prior to being on their own in their job duties. Within one year of hire, all employees are required to further advance their training through the University of Minnesota SSTS Program or the Minnesota Onsite Wastewater Association to become certified wastewater specialists which will ensure they are able to assist the company in managing any of your wastewater needs.

Cindy Tiemann & Jeff Tiemann

Cindy and Jeff are co-owners of Fiedler Your Pumping Specialists, Inc. While some couples may have a hard time working together this couple seems to have it figured out. Cindy is certified by the MPCA as a Type 4 wastewater operator, Maintainer and Service Provider. Her 30+ years as a Registered Nurse and more than 25 years in management have played an integral role in managing the operations of business. Jeff’s 30+ years in Farming have made him a master of many things that go hand in hand with running a septic maintenance company. From dealing with trucks and equipment repairs, to land application, crop management and working with landowners to name a few.

In addition to this company, Jeff and Cindy also own a Crop farm near Royalton and raise chickens for Pilgrims Pride.When they are able to get away from everything for a day or so, you might be able to find them camping at their seasonal campground by Sauk Centre or they just might just be home enjoying time with their children or their 3 beautiful grandchildren. After all when you work together all week and you get along well, you might as well spend fun time together too!
