Zeltwanger currently serves as the regional president, Community Banking Division at 1st Source Bank. In that capacity he is responsible for managing nine branches (five located in Marshall County) and approximately 80 employees.
In 2006, he was recognized with the Ernestine M. Raclin Community Leadership Award. Raclin, chairman emeritus of 1st Source Bank, strongly demonstrated the spirit of volunteerism throughout her career. The award was established to recognize others who have created an atmosphere where volunteerism is supported and encouraged.
Prior to joining the bank in December 2001, he served as senior vice president at Wm. Leman Company for 11 years and as vice-president at Farmers State Bank of Wyatt for four years.
LMC Class XIV member Nicole (Niki) Clemons nominated Zeltwanger for the award.  Clemons serves as a client services specialist at the 1st Source Bank Plymouth Banking Center.
In her nomination she wrote: “Ron Zeltwanger demonstrates daily the heart of a servant and a dynamic leader.  His passion is not only for his team of employees but for our customers and the communities we serve.  I feel that Ron leads his employees, customers, and his community, not by pushing or pulling them along, but by standing beside them and offering his support whenever it is needed. He has made 1st Source Bank a great place to work, and Marshall County a great community to live in.”
Seven 1st Source Bank Banking Center Managers enthusiastically endorsed his nomination for Leader of the Year.  Rene Burton, Argos and Winamac Banking Center Manager said it best: “What makes Ron an exceptional leader is his ability to coach his staff with patience and wisdom, inspiring each one of us to personal growth and service to others. He is full of energy, enthusiasm and fresh ideas which enables him to be a great problem solver and an inspiration to the people he leads.  He uses wisdom when correction is needed, not provoking us but challenging us to rise above the circumstances and become part of the solution.  Ron’s passion for others and for the community is evident in his lifestyle, his family and his relationships with the people he serves.”
Zeltwanger serves on the Board of Directors of the United Way of Marshall County. He is a member of their finance committee and financial stability project committee. He is also an elder at the Community Gospel Church in Bremen.  In the past, he has chaired the Bremen Division of the United Way annual campaign and was a board member of Leadership Mar-shall County from 2004 to 2006.
