Meet the Team



Geoff is a 1976 graduate of Miami University in Oxford, Ohio in which he earned a Bachelor of Science degree in Marketing.

He earned his first paycheck at the age of 11 years old working in the receiving department of the family owned Gregg’s Department Store that was founded by his Great Grandfather in 1885. At Gregg's Department Store's peak, it employed over 300 people and operated in a 200,000 square foot facility in Downtown Lima, Ohio. At age 16 Geoff moved to the Store’s Mens Department as a sales person and continued in that role throughout his high school and college years. Upon graduation from college, he became manager & buyer for the Mens Department of the Store. Upon the death of his father in 1983, Geoff became the President and CEO of both Gregg’s Department Store and Enzyme Industries, Inc. The Gregg family had made a long term commitment to keep its family owned department store in Downtown Lima while other retail stores left the downtown area for the malls. In 1985 after 100 years in business, Geoff made the difficult decision to close the family’s department store and focus his attention on Enzyme Industries, Inc.

In his free time, Geoff enjoys his beloved rescue dogs, golf, boating, and traveling especially to favorite places New Zealand, Israel and Kauai, Hawaii. He has been a lifelong and recently long suffering fan of the Cleveland Browns, and was a longtime season ticket holder. Recently he has gained an interest in becoming a Barbecue Pitmaster, but has a long way to go in becoming a master of that art. Another of his interests are in ancient prophetic manuscripts and how they relate to current events. Geoff currently resides on the beautiful shorefront near Sturgeon Bay, Wisconsin.
