My first impression of Liam was him walking into our nursing class joking about finally being able to make a bed and not having an excuse not to make his bed at home. At Mercy, he helped orient me and was great. His kindness, patience, and love for everyone just enveloped the entire OR. He would joke around with everyone and had a great sense of humor. I pray he is at peace as he is finally reunited with his mother and father.

Liam it’s been years since we’ve worked together, but you surely made an impression. One coworker I would never forget. A nurse with compassion, a great colleague to have on your team, always willing to lend a helping hand. A humorous soul with such a good spirit. I pray that you are at peace and have been able to reunite with your dear mother and father, ultimately with the Father. God knows and His will be done. I just pray that God wraps His loving arms around your family, wife, children, brother and all of your family and friends- comfort them and give them peace beyond understanding. Peace and blessings🙏🏽

Liam we started off as coworkers who became friends and then family. You were superman to my wonder woman. I can see you flying high except instead of a cape you have earned your wings. Praying for my sister Heidi and the kids.

Liam, we were like peanut butter and jelly. I never had to question how we would handle a situation in the OR because were always on the same page. I called a spaded a spaded and you loved to sugarcoat it but we worked well together😊. I am going to miss leaving you piece of paper on the keyboard and our conversation. I am truly going to miss you, my brother from another mother

Words cannot express the Joy and Love that you passed on to so many who had the Honor to know and interact with you. While we all mourn your passing, it has been uplifting to talk with so many of your friends and hear the stories that created so many laughs and tears. Your impact on people will be your Legacy. My prayers are for comfort and understanding for your family and friends. You are already missed my friend!

Liam and I worked together as technicians at the Washington Animal Rescue League. He could fill a room with laughter when he walked in and his compassion towards every animal he handled was amazing. He taught me so much. We stayed up switching the opening side on the refrigerator door for April Fools and it still opens on the wrong side. His family was his greatest joy and when he spoke about his wife and kids his whole face would light up. Sending my deepest condolences to his friends and family during this difficult time.

I had the honor and absolute pleasure to work with Liam at Mercy. We bonded immediately over having scrubbed for the same doc at prior hospitals. He was so kind and so funny. I always laughed around him. He was an amazing nurse and I enjoyed every moment working with him. My heart and prayers go out to his wife and children. 🙏🏻
I’m truly saddened by this loss.

Liam was a classmate of mine on our journey to our BSN. I enjoyed and looked forward reading his lively and clever discussion board posts. This tragedy has deeply saddened me, my prayers to his family and friends.
