I had the pleasure of meeting Denny through his wonderful wife, Maureen. We all shared some laughs, good food and drinks together. Denny had a sweet, calming soul and always brought a smile to his wife’s face when she spoke of him and we will forever continue to smile when we speak of Denny. My condolences and prayers to Maureen and family.

Den this is probably the hardest thing I have had to do. As a brother you always were my protector. It was great having a big brother always looking after you. We would walk to school together, you would make lunch for me and make sure I got back to school on-time. That was not always an easy task. Through life we grew closer as siblings and most important friends. I knew without a doubt that you loved me. I so wish we would have been able to take our trip together. We planned a trip of a lifetime and did not get to take it. I enjoyed the times through the years we did experience traveling. I will miss you answering the phone "is this my favorite sister" and I would say "I hope do, I'm your only sister". I am going to miss you every day until we are reunited again. I love you.

We first met Dennis about 3 years ago when he began flying helicopters at our school and providing maintenance services. Over the years we developed a close friendship with him and Maggi, wrenching on engines or kicking back at their house. He was such an interesting and generous guy with a great sense of humor. He will always have a special place in our hearts. See you in the sky Dennis. Love, Tyler & Tasha

My deepest most sincerest sympathies and heart felt condolences to you Maureen, family and friends. I had the pleasure of meeting Den just a few years ago after knowing Maureen for many from working together her and I became fast friends. Den was very quiet and you had to listen carefully he would say something hilarious in a group during a conversation and to bad if you missed it. He had a kind smile and very interesting stories, intelligent stories. I enjoyed the stories about he and Maureen the most. May those memories keep a smile on your face and a big hug around your heart.

My heartbreak of Dennis's passing can only be balanced by the blessing I was given to know him as a friend for 20-plus years. Those memories fly through my mind as if I was finally up in that plane that he could never get me on and look over the terrain of our friendship. The rivers of his caring ways and fields of kindness bring the joy and calmness his friendship gave me. But of all those views, my favorite is witnessing that mountain of love he had for Maggie. I will miss him forever.

Dennis was my husband, soulmate and partner for 32 years. He was a man of such integrity and never judged anyone; he chose to focus on someone's positve traits rather than the negative traits! He was inquisitive and always ready to learn something new. He would always try to help others and hope they would succeed. He loved me wholeheartedly & unconitionally; he treated me with repect and my happiness was his goal! He also loved our families and friends; he would do anything for them. Dennis was an honorable man, he will be so missed but never forgotten. Heaven has a very special angel among them now!!!!

Dear Maureen, You have our deepest and most sincere sympathy. We are so sorry for your loss. Know that you were the perfect companion, friend and wife, Denny could ever hope for. You two were a beautiful couple. We have had several special and fun memories with you both. Dennis was the perfect host, taking us for our first ultra-light plane ride. What a thrill that was! Darrell also has fond memories of taking Denny’s Harley motorcycle for a spin around the neighborhood. How about our evenings in our pools. Lots of laughs. Good times. He’s looking down and caring for you, now, Maureen. You will see him again, when God feels it’s time. Know that you are loved very much. Looking forward to spending time with you...darn Covid! I’ll be in close touch, as always, Love, Janie, Darrell and Neal
