What Clients Say

Testimonials

The impact of Corker Consulting is best reflected in the words of those we’ve worked with. From hands-on training to practical resources, our clients share how these services have helped strengthen custodial operations across their districts.

“In 2008, Dearborn significantly reduced the number of custodial staff to ensure that teachers remained in the classroom. Since that time, the quality of cleaning has declined. Concurrently, numerous additional responsibilities have been assigned to our custodial staff beyond their primary cleaning duties. Compounding this issue are the recent labor shortages we have been experiencing. Consequently, building staff, including administration, have exerted pressure on our business department to reinstate custodial staff in their respective buildings. However, the current budget constraints have prevented this from occurring. Your input has been essential for the district to assess our present staffing levels and determine the appropriate standard of cleaning that should be achieved.”

Mark Andrews, Director of Operations, Dearborn Public Schools

“Corker Consulting was instrumental in helping our district establish standards for custodial cleaning and detailing them in a easy to read manual.  This has been invaluable for our team as we navigate increased turn-over and limited resources.  I believe it was a good investment for us.”

John Lettang, Exec. Director of Facility & Custodial Services, Warren Consolidated Schools 

“I talked to a few custodians who all said they learned new things, felt invested in, and were glad to have the time to learn how to be more efficient and effective. Again, your ability to relate directly to our front-line staff is incredibly effective.”

Russell Bray, Director of Facilities and Operations, Kent ISD

“I highly recommend The Custodial training manual by Dave Corker as an essential resource for our custodial team. The comprehensive guide provides clear, practical instructions on a wide range of cleaning tasks. Daves handbook emphasizes efficiency, safety and best practices. The custodial handbook has helped my team improve performance and productivity. Members of my custodial team can now work with confidence that they are all doing the work correctly and efficiently. It is very valuable in training new custodians, it allows them to get the training they need and it gives them something to quickly refer to if needed.”

Michael Roehl, Director of Buildings and Grounds, Marysville Public Schools

“I am writing this recommendation for Corker Consulting.  Dave Corker has provided our school district with custodial staff training for many years, most recently with Corker Consulting.  The feed back received from our staff attending was excellent.  The training was tailored for each staff member according to their knowledge.  In addition, Corker Consulting created a staff training work book for our staff this school year.  This has also proved to be a valuable asset for our current staff as well as new hires.”

Cori Wiley, Maintenance Supervisor, Anchor Bay School District

“As school business officials we focus a lot of our PD in the classroom.

“I recently had my Custodians attend one of Dave Corker Custodian seminar, and it was a game-changer for me and my team. The sessions were incredibly insightful, offering practical tips and strategies tailored to the challenges Custodians face daily. Dave was so knowledgeable and engaging, and the real-life examples he shared made the content relatable and easy to implement. All my Custodians left feeling more confident, valued, and equipped to perform their role at an even higher level. I highly recommend the seminar to any Custodial staff looking to improve their skills and take pride in the vital work they do.”
