Our thoughts, prayers, and sincere sympathies are with the Cielak Family.

It was an honor and privilege to work with Ron at O'Briens. He was extraordinarily kind, generous, compassionate, patient, joyful, warm, and he laughed often.

He was truly a one-of-a-kind person. Our hearts are broken. He will be missed dearly.

May there be some comfort in knowing that Ron was beloved by Everyone and his legacy will go on forever.

God Bless Ron and his Family.

Cielak Family - You are in the thoughts and prayers of colleagues at Aon that had the pleasure of working with Ron. He was such a kind soul and an instant friend and partner, always willing to lend his time to help out. His genuine smile and positive attitude leaves a lasting impact on us all.

I was first introduced to Ron in January of this year. I had just arrived in Chicago from Ireland and was beginning an internship. His generosity and friendship knew no bounds as he helped us to settle in. He had since grown to become a dear friend and mentor who helped foster my own passion for social justice and politics like no teacher could. Our conversations both in person and over the phone taught me valuable life lessons which I will always carry.

I hope Ron’s family and friends can take comfort in knowing that Ron’s impact was immense and far-reaching. Thank you for everything Ron!

Odhran Whelehan.

My thoughts and prayers are with the family during this time of loss. Ron was a close friend of mine at Aon and I am so blessed to have known him. He knew my family, he knew my 5-year old son and always brought him candy, so of course Noah loved him too :) I am devastated by this loss. He was such a kind person and always cheered me up no matter what. My deepest sympathies to his family and I will be remembering him always.

Sincerely, Nicole Presperin

I feel lucky to have gotten to know and work with Ron at Aon the past several years. I have to say that Ron was one of the nicest and good persons I have ever met, and to me that is about the highest complement to give. I am so sorry for your loss and you have my deepest sympathy.

I grew up with Ronnie, actually my brothers and I grew up with Ronnie and his brothers, like a little gang of brothers. We all lived in the same building in Albany Park, and hung out at nearby Jensen Park. I was 3 years older than Ronnie. He wasn’t a big guy, but he wasn’t clumsy either. But he didn’t get into the sports scene; the mainstays at the time being basketball/baseball. Instead, he cheered us on the sidelines. With his shock of hair (he had a lot of hair then) pixie-face (a Cielak trait) and tan, and the girls around him, he looked like an up-and-coming teen heartthrob….awesome!

Ronnie was an easy going person, not confrontational at all, a kinda low-maintenance friend. My regret is that we grew apart and didn’t see much of each other in the last 20 or so years. Thanks, Ronnie, for the memories!

Ron was loved by all at Aon. Ron brought a smile to everyone he came across. Ron was a loyal and incredibly collaborative employee that everyone would go out of their way for. We are truly heart broken with this sudden news. Aon colleagues will always remember Ron’s positive attitude, smile and gentle heart. Rest In Peace Ron.
In memory,

To Ron’s Family,

I had the great joy of meeting Ron through St. Vincent’s and then at Aon. He was always so kind, thoughtful of others and ready to reach out to support his colleagues. He was a tremendous supporter of Aon’s apprentices and offered a welcome to Aon to those who needed it most.
He was also very good to my son Finn at O’Briens. We will miss him

Ron will be greatly missed. He had such a passion for his work, especially when that work brought him together with our Summer Interns and College Graduates. He wanted to ensure they had the best learning and experiences. I shall miss working with him and especially miss our lunches together.

My thoughts are with the Cielak Family at this time,
