Michael Dwaine Callahan

June 17, 1959February 19, 2021

Michael Dwaine Callahan, 61, passed away on February 19, 2021 after a relentless and heroic battle with lung cancer.

Michael was born on June 17, 1959 in Martinsburg, West Virginia by his parents, the late Earl and Audrey Callahan. He was the youngest of three children. Growing up, Michael enjoyed playing football and baseball. He graduated from Martinsburg High School in 1977 and married his high-school sweetheart Ruth Anne (née Kilmer) in 1980. Michael originally attended Virginia Military Institute on a football scholarship before transferring to West Virginia University. He graduated in 1981 with a degree in Electrical Engineering, and almost immediately after college, Michael worked for DuPont until 1997. From 1997 on, he worked for Accenture. Michael and Ruth Anne eventually grew their family to include three boys: Carter, Hunter, and Bee. Sadly, Ruth Anne passed away in 1998.

Michael’s work gave him and his family the opportunity to live in Thailand for two years and share many unique and exciting experiences together, whether it was sharing the pain of spicy Thai food or enjoying the gorgeous countryside of France.

Michael met his current wife Lisa (née Zirolli) in September of 2012 and were married almost exactly one year later. Since they met, they were inseparable. They loved spending time at the beach and shared their love, memories, and energy with all of their family and friends.

He is preceded in death by his brother Charles “Buddy”, his first wife Ruth Anne and their daughter Emma Catherine, and his nieces Wendy and Shelley Price.

He is survived by his wife Lisa; their three sons: Carter and his wife Alyssa, Hunter and his longtime girlfriend Kaitie, and his youngest son Earl “Bee”; his eldest sister Betty “Jean” Fulk and her husband David; cousin Skip who was like another brother to Michael; together with many other nieces and nephews.

Some of his favorite hobbies include things like woodworking and building furniture. He loved paying bills and keeping up with the big old house he once owned. He was a very kind and quiet man with a great sense of humor. He loved his family very much and would do anything he could for them.

A Memorial Mass will be held Wednesday, February 24 at 10 A.M., with a visitation at 9 A.M. at St. Isaac Jogues Catholic Church in Wayne, PA. Alleva Funeral Home, in Paoli, is assisting the family with arrangements.

In lieu of flowers, memorial contributions can be made to the University of Pennsylvania via the link below.

Dear Lisa:
Laurel and I were saddened by the news of your husband’s death. Please convey our condolences to the family.
I am pleased I had the chance to meet him. The depth of your grief shows the strength of the love the two of you shared. Just know that, someday, the joy brought by your memory of him will outweigh the pain of your loss.

Dear Mike. You are the best of the best! You will be missed by all whose lives you touched. I am so proud to be one of those lives touched by you. I’m hopeful that all of us can take from you a small portion of the love and passion and compassion that you exhibited daily. To Lisa and the rest of Mike’s family, I have no words, except that you’re so lucky to have had Mike for the time that you did. Mike had a way of making everyone around him better. Peace.

I came to know the Callahans in a time when I was transitioning towards retirement. I spent a few months with them. Which included getting stuck in the Mud and watching the Super Bowl with Mike the year the Eagles won! The kindness of this couple came out of a place of Great Love they had for each other. Thank you Mike and Lisa! I miss you.

I had the opportunity to work with Mike for over 15 years. Mike was always a Gentleman and Professional. Mike was a Friend and Teammate. I had the opportunity to speak with Mike few days before he passed and as he was fighting to hold on, he still found the strength to ask about all of you and for me to say hello to you all.
Mike will absolutely be missed. - Ade Ojediran

I am shocked and very sad to read this news. Mike was such a nice person to work with, always calm and ready to help. May his soul rest in peace. We will definitely miss a wonderful person in the Accenture family.

I am so very sad to hear this news as well…I have such fond memories of Mike and loved his humor.

With my deepest sympathy and prayers for his family,

I am unbelievably sad and have a heavy heart today. Mike had an incredible soul, was deeply kind and a joy to be around. I was lucky enough to have worked with him on many deals throughout the years and I enjoyed every one of them. My deepest condolences to his family.

This is very said to hear. I very much enjoyed working with Mike and have fond memories of Mike and I (along with others on this mail) working together in Beverly Hills at AECOM. Mike will very much be missed.


Really sad to hear this… Mike was a kind soul who I had the opportunity to work closely with, for which I consider myself very fortunate. Its not easy when folks leave us before their fair due time… I wish peace for Mike and strength for his loved ones… I will truly miss him and he is leaving a void here at the firm that will be hard to fill…

Dear Lisa and family,

Mike was more like my second son than a brother. I loved him from the minute he was born and we stayed very close because he and my own son, Skip, were close in age so he spent a lot of time with us and we took him on our family vacations . He was a kind, sharing gentle soul, had a terrific dry sense of humor and Martinsburg was always home no matter how far away he lived and worked. He told me just several months ago to ask the prayer chain at our childhood church to keep him in their prayers because Martinsburg would always be “home” and Otterbein United Methodist Church would always be his “home church”. It’s how Mike was - once his friend - always his friend. Both of my daughters loved him dearly and I believe they, with the rest of his family and friends were there to greet him when he passed away and entered Heaven’s gates. He will live on in my heart until we meet again. I will miss his calls especially after his illness and he had extra time, we would talk and share memories of times gone by. Rest In Peace Mike - I love you ❤️

Lisa and boys, words can’t express my sorrow at the loss of your husband and father. My heart hurts for you.

Lisa, Mike was such a kind and wonderful man and the love and joy that you brought to each other was truly magical. I loved being with you both to witness it. Your wedding will remain always at the very top of my list. The love story of you and Mike and the boys was such a blessing.

It was not nearly enough time together but I pray that your memories bring you some comfort.

Sending you all my love and prayers. Donna
