In Memory of Matthew Ridley

We are heartbroken to announce Matthew Ridley passed away peacefully on Wednesday, February 1, 2023 at the age of 43 years.

Matthew was a loving, proud and devoted father to William and Andrew and his four legged children Rocky and Gus. Much loved son of David and Leianna. Predeceased by his mother Deborah. Appropriately inappropriate brother to Marissa, Jessica, Jacalyn, Wilson and Meghan. Uncle Matt to Liam, Myles, James, Charlie and Grace who will always remember his ‘Potty Talk’.

Since 2003, Matthew was an appraiser with Ridley & Associates. Other than his family, his love was cars, in particular the Mercedes Benz AMG. He was also a gifted rapper, bustin’ rhymes at any moment. He could make light of any difficult situation, bringing joy and laughter to those around him – which would have made this situation much easier. Matt had a heart of gold and would help anyone. He was kind, caring and loyal to his family and friends. Words cannot describe how much you will be missed Matt!

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.
