Kenneth M. Dennison – 7/24/2020

July 29th, 2020

Kenneth M. Dennison, 70, of Unionville, PA passed away on July 24, 2020. He was born in Springfield, OH to Kenneth and Mary Dennison. He served in the US Navy as a hospital corpsman during the Vietnam War and graduated from Ohio State University with a Bachelor of Science. He was the first member of his family to attend university and believed deeply in the value of education, a value which he passed to his children. He completed his MBA at Bowling Green State University and he worked in the pharmaceutical industry for Wyeth, where he held a variety of positions as a sales executive. He moved several times with his family throughout his career before settling in southeastern Pennsylvania.

He lived fully, with passions for food, travel, fishing, running and music, and keen interests in science and civil war history. He was a talented guitar player and vocalist, a love shared in many a jam session with friends and family over the years. He was a lifelong runner, completing multiple marathons in younger years. He was a loyal OSU alum and avid fan of Buckeye football. He was also deeply spiritual, an active member of St. Malachy’s parish and a believer in the positive power of meditation. His daily practice of gratitude brought him much joy in retirement, a gift which he shared with others through his volunteer work.

Family was the heart of his life; he was a loving husband, father, grandfather, brother and son. He was predeceased by his father, Kenneth L. Dennison, and sister, Linda Guerra. He is survived by his wife of 47 years, Phyllis Dennison; children, Kirsten Dennison (Stephen), Scott Dennison (Shari), Matt Dennison (Heeyeon), Beth Dennison (Alex); mother, Mary Dennison; brother, Gary Dennison; sister, Kathie Dennison; beloved grandchildren, Oscar, Sylvern and Neko; and many dear friends.

His service and burial will be private at the convenience of the family, donations may be made in his honor to the Catholic Charities Appeal of the Philadelphia Archdiocese or the Chester County Food Bank, (select tribute giving option), 650 Pennsylvania Drive, Exton, PA 19341 by mail.

An open letter from Phyllis:
Ken loved you all. His sudden death is surreal. I am so grateful he expressed his wishes to me recently, as we had lost several loved ones of late. It was his wish to have a private family service. Of course, this coronavirus cloud has impacted all our lives and plans. We treasure the memories and hope for all to find serenity in knowing that Ken lived life to the fullest every day. He would want you to know that on his last day he ran his last mile in 8 minutes and 41 seconds. He couldn’t have been more happy, joyous, and free. May his soul rest in peace with his God and his spirit continue to live in you.

    Dear Dennison Family,
    I never met Ken but heard many wonderful stories from his daughter, Beth, who has become my best friend/soul sister here in beautiful VT. In Beth, I have found a deeply reflective, kind and loving friend and I imagine Ken had a very similar demeanor. She has blessed my life in so many ways and I am so grateful for our friendship. The love Ken must have shared with his family has spread throughout the world and touched so many lives just like mine. My deepest condolences go to his entire family.

  • By Jean Honsa on

    Ken was wonderful. I am so sorry, Phyllis and family. I have many happy memories of getting together to play and sing. I always think of you both when I hear The Battle of New Orleans. I always think of Ken when the topic of marathon running comes up. Lots of good memories. He will be missed by people near and far. I will keep you all in my thoughts and prayers. With love.

  • By Steve Vandevelde on

    So sorry to hear of Kens passing. He was a great boss, leader, peer and mentor to me throughout my career. Ken had a passion for the vaccine business, his real passion was always his family. While our paths haven’t crossed since we both retired I’ve thought about him often. He was always positive and supportive and the only time I ever remember getting into any serious disagreement with Ken was when Michigan played Ohio State!
    You are all in our thoughts and prayers.

    Phyllis and Family,
    It was hard to get the news from Walt Barrett about Ken’s passing. He was one of my close friends in high school and I spent many days in his basement with hm and Carter and others singing, listening to albums and watching the TV series Batman, etc.
    I was so pleased that Julie and I were able to sit next to Ken and you at a table at the class reunion several years ago. It was fun to learn about your lives and reminisce about some good times in the past. I retired from teaching at a Bible college here in Missouri 31/2 years ago. How quickly the time goes.
    Ken was a fine long distance runner in school (880 I believe!). He has now finished the course.
    Phyllis, our prayers go out to you and the rest of the family.
    Larry and Julie Pechawer

    The Gentleman Ken will be missed. His great generosity with time and compassion benefited so many; us included. Our deepest condolences Phyllis. May you and your family be well in spite of this sudden sadness handed to you. We are here, if we can be of any help.

  • By Brian Fetzer on

    Dear Phyllis,
    Mari and I mourn the passing of Ken and send our love and condolences to your family. We worked together several years in the mid-90’s, stayed in touch and maintained a friendship over 25 years. Ken was a talented leader, quick to laugh and a teacher of life’s lessons. We will miss him.

  • By Tom T on

    My partner in pinochle and guitar building, regardless of how we were doing, Ken always had a smile on his face and a chuckle in his voice.
    Phyllis, I smile when thinking back to Ken playing guitar for the neighbor’s kids after our last brisket barbeque dinner at the beach. Good times and wonderful memories.

  • By Bill Campbell on

    Phyllis and Dennison family,

    I had the sincere pleasure of getting to know and working with Ken for many years at Wyeth. Ken was a Leader, a Developer of People, a Role Model, a Gentleman and an incredible example to all on how to always do the right thing. The physical world has lost a truly great person in Ken. I know however, that he will be looking down and continuing to guide his family.and friends as he always has. Our prayers and thoughts are with you and your entire family.

  • By Hugh Hyatt on

    My heart goes out, particularly to Phyllis, but also to Ken’s extended family and all his friends who, like me, were so surprised and devastated by his passing. In the days since, I’ve been especially thinking about Ken’s humility. He had many talents and gifts, but was always willing to hear new ideas and opinions he didn’t necessarily share. He never bragged or showed off in any way over the 12 or so years I had the privilege of working with him.

    This world has lost a brilliant star, but another world has gained one.

  • By Linda Carter on

    Phyllis and Family,

    I want you all to know how deeply I relate to what you are experiencing with the loss of Ken. He was a marvelous man – so caring and easy to relate to. He was the lifelong friend of my husband who tragically passed similarly in 2011. They both loved the guitar and their childhood memories and the music of the 60’s and 70’s. They had an unconditional acceptance and connection that few experience. I feel privileged that Ken and Phyllis continued to go out of their way to schedule visits with me when they were back in Ohio. Friends are the anchors of our lives and we will all miss Ken’s friendship and great smile.

    Phyllis and Family, Praying God will give you strength, peace, and the gentle comfort your hearts need.

  • By Dale Dennison on

    Phyliss, and children, though we never met I wanted to express my sympathy to you. God Bless Mike. As 1st cousins we lived close to each other on York st Springfield Ohio. Mike was very kind to me and my brothers and sisters. As neighbor’s we lived in what was a tough part of town but we all made the best of it in those early years. I fondly remember Mike playing the guitar and singing. Recently , Mike and I had connected on Facebook and had some good discussions of family genealogy and some his spiritual passages that he shared with all of us. Again God Bless to all! So sorry for your loss. Dale

    Dear Phyllis & Family,

    Your phone call last Saturday evening truly shocked us. We have many fond memories of Ken beginning with our pilgrimage to Ireland and most recently crossing paths along the walking trails in Unionville. In between, there were mutual home visits and numerous Sunday mornings at St. Malachi sharing life experiences. We’ll miss his friendship and enthusiasm. Our deepest sympathy. A good man has left for home!

  • By Tim Stoltzfus on

    my thoughts, prayers and love are the entire Dennison Family. My life is surely better because Ken was a part of it. He is a great man and what a great example of how to live this life and enjoy it!! May God bless you all in this time of loss.

    Forever grateful, with Love!!

    I am so sorry about the passing of Ken. I knew him as the RBD I reported to at Wyeth and he gave me my opportunity to go into vaccines back in 2004 where I am still working. I learned a lot from Ken and he had a great Warmth and kindness when sharing with others. You are all in my prayers.

  • By Jane DeWitt on

    Phyllis, I sat next to you and Ken at the area 59 banquet in November 2019. It was an absolute delight to meet and speak with you that night while Ken was ‘taking care of business’. I am utterly devastated to hear of his untimely passing, my heart goes out to you. Praying for peace and strength for you in this unfathomably difficult time.

  • By Ginny Hudson on

    I knew Ken from working at Wyeth. He was such a gentlemen & loved talking to him. So sad to hear this. He was truly loved by all. Rip dear friend.

  • By Kim Haupert Bencker on

    My thoughts and prayers go out to all of you. Ken was a great leader, and a special mentor to me. I will always remember my first interview at Wyeth with him, and his belief that I could join his amazing team. He was very proud of his family, and I extend my deep condolences to you all. I hope his legacy lives long with all of you.

    With sympathy,

  • By Bill Tousius on

    My deepest sympathy to all of Ken’s family and loved ones. Professionally Ken was a superior mentor to me when he hired me for my first Sales Manager position at Wyeth. Personally I knew Ken to be a warm, caring person who was happy to see others achieve in their lives. Great sense of human that his eyes would light up when he laughed . My life is richer having known him .

  • By Jackie &Glenn on

    Sorry to hear about Ken. WE will keep praying for you and your family.

    Our life are so short sometimes we all forget to enjoy each moment. Somehow, I do not think Ken was one of those who forgot to enjoy the moment.

  • By Stephen Grossman on

    Condolences to Phyllis and the entire Dennison family. I worked with Ken at Wyeth for many years. He had a positive influence on my career as well as on many other young professionals within the organization. Ken was a great mentor and motivator. He was an ideal source to go to for any advice that one might need. It was truly an honor to have known him. May he rest in peace.

  • By Hank Hoppin on

    We never know how much someone means to us until they are gone. Ken was a loyal Buckeye fan. I happened to be a Illini fan so… one yr. we saw a game @ “The Horseshoe.” It happened to be the game Eddie George broke Keith Byers single game rushing record. To Ken’s delight Illinois suffered a terrible beating. He will be missed.

  • By Rita Downs on

He was a very gracious and patient mentor and a wonderful steward of the business. He was always so respectful of all he worked with.It was an honor to have known him.
    I hope the next few weeks go easy on you and that you can find comfort in each other and in close friends.

  • By Bob Headley on

    We met early in life, were fast friends, sang together in a couple of folk groups, played music atop drive-in movie theatre concession stands, took trips together, but essentially parted ways when military service took us in different directions. I have a photo that I cherish: Ken, Mike Beekman, and I on a couch, arms around each other’s shoulders, grinning for the camera. Mike, too, is gone now. Time and family and careers separated us all, but I have no problem conjuring wonderful memories of a fine friend, a boon companion, and a string influence on the man I became. Thanks, old friend. I miss you.

  • By Nelson Vecchione on

    My condolences to Phyllis and the entire Dennison family at this difficult time – May God help you to find Shalom. Ken was a model of service in our community and I know he lived his life for the benefit of others. He was happy, joyous, and free and I am sure that he is now resting with the Lord. He will be missed by many, but celebrated by more! Rest In Peace

    Phyllis and family, you are in our prayers, this is a sad day as Ken was one of my best friends during high school days. I was not the musician but I loved hearing him play and sing. He will be missed by many.

    • By Jay Houser on


      I had the honor of working with Ken at Wyeth. He loved his family and would talk so fondly of you and the kids when we were riding in the van trying to take down Similac. He was the first man to give me a hug and offer help when I was promoted. Prayers of comfort for you and the family. Such a kind family man.


  • By Gary Dennison on

    Ken Dennison was my brother. He was 5 years older then me, as a result we were not that close growing up. He was attending OSU. when I was in Jr. High School. Through the years how ever we got to share our lives and the raising of our families. I came to admire my brother, not just because he was my brother but because of the wonderful man he was. He loved his family so much. He and his wife Phyllis did almost everything together and their marriage should be a testament to true love. He was so happy in is retirement and so enjoying his beloved grand children. He was to young for this. My heart is breaking, I will think of him and miss him everyday. Mostly my heart breaks for his wife and family. May he rest in peace, He will never be forgotten.

  • By Ed Madalis on
