President – Surety Bonds Inc.

Mark Drengler
Mark started his career in the surety business in 1978 after graduating from Adrian College with a double major in Business and Accounting. Not wanting to be an accountant (too boring) a position in the Surety Department of St. Paul Fire & Marine Ins. Co. presented itself and off to Detroit he went. For nine months, Mark was a Bond Trainee and in early 1979, he was transferred to Springfield, MA and served as a Bond Underwriter and Field Supervisor, still with St. Paul.


In 1984, Mark took a Manager Position in Columbus, Ohio with Peerless Ins. Co. During his five plus years there, the Columbus Office was name “Bond Office of the Year” two years in a row (this hadn’t been done previously in Peerless).


In 1989, the agency side of business called and off to Surety Bonds Inc. Mark went. Mark worked for and with John Koetz (founder) until 1995. In November 1995, Mark bought 100% 0wnership of Surety Bonds Inc. Besides running the highly successful agency, Mark has devoted his time to the industry serving as President of the Surety Association of Ohio for nearly ten years and also as Regional Vice President and Director of NASBP for six years. Mark has testified in front of the Ohio Senate and been involved in numerous issues fighting for the surety industry.


Mark believes that reputation in this business is something one never wants to lose. He adheres to the theory that surety is a 0% loss ratio business. His job is to take top quality bond business to the underwriter. In his career, he has not experienced a bond loss, a comment that cannot be made by many others and is something that he is extremely proud of.
