My sympathy to Doak’s family at this difficult time. I had the wonderful privilege of working with him at Lone Star College Kingwood for many years. I was the Disability Services Counselor there and had the opportunity to interact with him frequently. He was one of the best instructors I worked with in my 30 year career there. He was so student focused and always looked for ways to make math less intimidating and more enjoyable. Plus, he was just a joy to be around. We would sit in my office and visit about many different topics and life in general. Most importantly, I considered him my friend. God bless always!
