John was a very good neighbor for my Mom, Florence Duso. She always felt at ease knowing he was just a few doors away. My Mom spoke highly of him, and his sermons too. Ron Duso

Dear Karen, Ellen, and Catherine, I am so sorry that I wasn’t able to come to John’s funeral.
I had foot surgery last Thursday, and am not able to walk or drive.
But, it is very important that you all know how much I love and care about you all, and how much John meant to me.
We had lots of conversations about how much our families meant to us, and I know he loved you all so much.
He was a wonderful, kind, and sweet man, and I will always be happy to have known him. ...

My dear John, how much fun we used to have, how many laughs. We agreed on so much, and argued about much more. I will miss your constant Facebook Messenger posts! You will be missed my friend. Thank you for all the years knowing you. Karen, Carol, and families my heart goes up to you. Blessings of peace and comfort to all of you as you go through this tough time.

I worked with John at AC and he also was our photographer at our wedding in 1980. I have not seen him in many years but he was such a kind man! My condolences to all of his family.
