1952 – 2018

With great sadness, we mourn the loss of our friend and partner, Jim Lang.

Jim was an exceptional leader and trusted advisor to our team and our clients for more than a decade. His experience, wisdom and mentorship will be missed.

He was dedicated to his family and to helping others in our community. He was an adjunct professor for Lindenwood University, served on the advisory board for Enterprise Bank in St. Charles County, and was President of the Board of Directors for BCI, a business employing adults with disabilities.

We celebrate Jim’s optimism and enthusiasm for serving people.
