All of my colleagues at FOSS North America say the same thing, Michael was a great guy. He had an energy and light. He was always kind, professional, and very concise. He will be greatly missed. My heart goes out to all his family and friends.

Mike was a wonderful friend. He and I grew up together on Ricardo Road in Mill Valley, where our days were filled with mailboxtomailbox football games, baseball with home plate right in front of his house, kickthecan, tag, and the occasional dingdongditch. We played until the dinner bell rang.
Mike was a great athlete, but an even better sport. As Tim and Tom grew up, Mike always included them—he was a terrific big brother. Walking to Strawberry Point School with him was something...

Lighting a candle in loving memory of Michael. His warmth, humor, and genuine kindness made every interaction special. He will never be forgotten.
With love and respect,

Mike always had a kind word, a friendly smile, and a way of making people feel seen. Those small, steady kindnesses leave a lasting mark, and they are how he will be remembered by many of us.

Tio Mike you were a huge part of my life growing up. My coach for little league. The person that got me into the Giants and 49ERS!! Life time fans of them both. Im going to miss your funny way of being with us as kids and all the love you showed us. Your giant T-shirts we would borrow for sleep overs... the number of times we would be playing dark tag as kids in the garage with all the cousins! Playing pool. All the nick names you gave us as kids. We love you and will forever miss you, but...
