I am so saddened to hear of Tony's passing. I've known Tony through to Dataflex community for 20+ years and can say, without a doubt, he will be sorely missed.

He was always supportive of the DISD community and a welcome presenter, (and entertainer), at our events.

Karen & family, our prayers are with you all. Tony has left a big hole to fill in our world.

God bless.

My Dear MacKay family,

To me Tony has always been larger than life. He lived and loved life to the fullest. He was a great mentor and friend. He was the go-to guy that could solve the problems that no one else could. But more than anything else, Tony was a really good man because he cared so deeply for others. Nothing upset him more than if he felt that someone was being sorely treated or not getting a fair shake. He was a good man to have on your side. And he was a great sounding board for me as I contemplated my retirement last year. Tony will be sorely missed.

Dear Karen andFamily, We are so sorry to hear about Tony. What a special and talented man he was. Our fondest times and memories of coming to parties or jam sessions in your basement or at Danny an Missys or at the lake. And some fun times on the river. Even the one where your RV got stuck. At camp ground and we got rained out of the campground. And if Im not mistaken we shared a room with you and Tony and I dont remember who else. We had to stack alot of bodies in rooms. Because they were full . Those were good memories. And watching you guys become grand parents for the first time. What joy you both bad in your hearts. Its hard my friend to lose your spouse I'm sure. I can't imagine.. Words can't take away the sadness you feel. But I do want to leave this with you friend. My prayer and hope is that you remember that your loved one is in Gods care. We are praying for you and the girls. I am here for you My # is 816-217-6619. Love Always sandy and Steve Kamolz

Tony was a one of a kind soul, and he was one of the most genuine people I have ever met. I was very lucky to count him as a coworker and most importantly as a friend!

He was always so full of life and fun loving, and was always ready for adventure. Whether that adventure was hijacking a piano from a ballroom , or getting chased out of a hotel room for singing too loudly at 4am on the balcony, or driving around town all night because he needed some chuck, singing just one more song or simply just being the great guy he was; that was adventure enough. He was always the brightest light in any room he was in.

He will be sorely missed by his family and friends. When I think of Tony I will try not to be sad, he wouldn't want that. He would want to remember the good times. I will do my best buddy.

There are simply not enough words in the dictionary to describe how amazing Tony was and how much I always enjoyed my interactions with him. From the first time I met him, he was like a long-lost friend. A man who never met a stranger and was always sincere and kind. Tony always reminded me, through his own lust for life, how important it is to seize the day and be yourself.

He will be deeply missed as a coworker, friend and most importantly; an amazing soul. Heaven gained a one of kind man who will assuredly bring more laughter and joy to those who have gone before us.

Tony aka 'Mac' to me, was my 1st cousin and dear friend. He was just 4 yrs older. We grew up together in Bowraville, Australia. Our families moved to the Kansas City area 2yrs apart in the early 1970s. Our families were very close. Mac was like an older brother to me and my 2 younger brothers, Shane (RIP) & Mick. There are just too many awesome memories in my head to go into. I will say I am so proud of the man he always was. In a conversation a few weeks ago he made it clear that he had a great life, wife and family. He had made his peace. He was not ready to go but if he did, he knew he was going to God's house. He was one of the most active and fit men of his age. His zest for life was admirable! My heart & prayers for Karen, daughters, sisters and family. We will meet again 🙏❤️

I was a coworker of Tony for the past 16 years. It is hard to express in words how I delighted to work with him on various designs or issues we encountered. Tony always got the hard stuff and I marveled in how he dissected problems and even under high stress still made me laugh. I had him out to our home in Arizona to play guitars and drink beers, or was it the other way around? We played and laughed for hours. We was an impressive musician and prided himself in playing accurately with soul. We stopped playing around 11pm and I was contemplating heading to bed, we both had work the next day, so I would have to send Tony back to his hotel, next thing I know, he has the guitar back in his hands and says, "what you tired?" Well you could never say No to Tony, we played into the morning...

I know Heaven sounds a lot better these days, and all the Angels are laughing more..

Love ya Man,
