What I will remember most is that Jack always kept an open line to Shawn & I. He reached out, expressed his love and caring for us despite what was going on in the background. He took the high road and did what he thought was right. For this, we will never forget. We love and miss you Jack. God speed.

Dad, our hearts are so heavy right now and will be indefinitely. You fought a good fight and went out like a champ! Thank you for being my dad and being the best papa to C and C! Conor misses you terribly as does Caitlin. We love you and until we see you again. Watch over us from Heaven!

My deepest sympathy to The Brennan Family. I loved talking to Jack. He was always so upbeat, cheerful and a had sense of humor like no other. I will Miss Jack at all our holiday and special occasion get-togethers. You were a great dad and great Papa. We will keep you alive in the hearts of C and C by keeping your memory alive and always talking about happy memories. My love to all.
