In Memory of Bob Kosar

It is with great sadness that we at Ridley & Associates acknowledge the recent loss of our valued colleague and friend, Robert J. Kosar on Sunday, October 9, 2022.

Bob has been with Ridley & Associates since 2004. In his time with us, Bob specialized in the appraisal of service stations and throughout his career honed his craft and advanced his skills. Bob gained recognition from his clients as providing highly skilled analysis, reliable opinions, and trusted advice. For this, Bob gained the recognition he deserved from major lenders, and earned the respect of his colleagues.

Bob developed many close relationships with the individuals he worked for and with and was loved for his candid and very personal honesty. He will be remembered, and he will be missed.
