About Dan, Owner and Operator 

About Wonder Janitorial Service - Commercial Cleaning Company Livonia Michigan - suit2Dan Wenderlich’s true passion is cleaning facilities of any shape and size. His story of turning a passion into a profession is unique and worth sharing.
In 1981 while pursuing his undergraduate degree, Dan had a part-time job cleaning academic buildings at his college. He thoroughly enjoyed the work—making what was once dirty shiny like new. He felt great satisfaction in restoring a facility to its original state of cleanliness.
Dan graduated from college and chose a career in the banking industry where he excelled. He maintained a side business of janitorial services because he still was passionate about cleaning facilities. After 17 years in the banking industry, and after being promoted to Assistant Vice President of a regional bank, Dan decided to pursue is true passion full-time.
Dan founded Wonder Janitorial Services in 2006 and is truly pleased with his decision to leave the banking industry. He is dedicated to his company and thrives on exceeding his customer’s expectations. For Dan, every minute spent—managing and growing his business, is a labor of love that he genuinely enjoys. He truely wants his customers to "Wonder what they did without him."
