Katy Dillwood wrote a sympathy message

“I was lucky enough to meet Mark and his lovely wife Sydney during the construction of their home in Santa Rosa. What an interesting man! I learned a lot and enjoyed some fun banter with him over the past two years. It's not fair. I've had too many friends and family that have also had to face the same challenge as he did. Mark was an inspiration, and he will be missed. Hugs to you and your family Sydney! Katy Dillwood”
