Life of Jon Hackenyos, DO

Jonathan William Hackenyos was born at Abington Hospital, Abington, PA, on May 17, 1971 to William Jonathan Hackenyos and Eileen Dougan Hackenyos. As an only child, he grew up with a close relationship to his parents and enjoyed life as a typical suburban child in Horsham, PA.

He participated in various sports in the township and high school. Jon and his dad also were part of a group of dads and sons in the YMCA-sponsored Indian Guides/Trail Blazers. Their tribe continued to meet and plan camping trips until the youth went off to college. The dads maintained their group for many years after. “Jolly Jonnie”, as he was called by his parents in early childhood, had an engaging personality and readily formed deep friendships throughout his life.

Jon graduated from Hatboro-Horsham High School in 1989 and from Syracuse University in 1993. He received his DO degree from Philadelphia College of Osteopathic Medicine (PCOM) in 1999 after simultaneously studying for an MBA which was awarded by St Joseph’s University in 1997. Jon was also a proud Freemason with his father.

Jonathan and Linda Lee Crook were married in May 1997. After completing an internship in Philadelphia, Jon and Linda moved to Arizona where he served a residency in Internal Medicine at St Joseph’s Hospital in Phoenix, including a year as co-chief
resident in 2003-2004.

I read of a man who stood to speak At the funeral of a friend He referred to the dates on the tombstone From the beginning…to the end He noted that first came the date of birth And spoke the following date with tears, But he said what mattered most of all Was the dash between those years For that dash represents all the time That they spent alive on earth. And now only those who loved them Know what that little line is worth For it matters not, how much we own, The cars…the house…the cash. What matters is how we live and love And how we spend our dash. So, think about this long and hard. Are there things you’d like to change? For you never know how much time is left That can still be rearranged. If we could just slow down enough To consider what’s true and real And always try to understand The way other people feel. And be less quick to anger And show appreciation more And love the people in our lives Like we’ve never loved before. If we treat each other with respect And more often wear a smile, Remembering this special dash Might only last a little while So, when your eulogy is being read With your life’s actions to rehash… Would you be proud of the things they say About how you spent YOUR dash?

A Final Goodbye?

Memories can sometimes be hard to recall on their own. Yet when you look at a picture, you are immediately transported back to a moment in time. Like the picture of my dad and his best friend, Dr. Jon. As I think about that image, the memory comes back to life… that blue sky and sunny day. Everything seemed perfect. But behind that perfect Arizona moment was something tragic. Reflecting on the happy times makes it easier to face hard ones, and this is what I am doing as I remember the day we said goodbye to Dr. Jon.

As we drove up that morning, after thirty days in Arizona, everything seemed to be different, yet somehow the same. The hacienda-style house was still the same, the street was still lined with stucco homes, and the same brightly colored Mexican tiles still ran along the wall. It was still Dr. Jon sitting there, but at the same time he seemed lost. He was on the porch reading a book, and when he got up, his outside features looked the same but all tired out, like a wave knocked him to the ground, his voice was so subtle yet… as he came up to us, it was like a barrier was between us.

“Glad you came by before you headed cross country,” Dr. Jon said in a faint voice. “Don’t come any closer, I don’t want you getting sick,” he cautioned.

“We have to say our goodbyes from a distance because Dr. Jon had a treatment yesterday and we don’t want him to catch anything from us and we can’t get near the radiation, that’s why we gave him big hugs on Sunday,” Mom whispered in mine and my brother’s ears.

“Yeah Jon, it’s just like when we were kids, I keep turning up like a bad penny,” my dad joked. Then he and Dr. Jon stood and looked at each other for a long moment.

That day seeing Dr. Jon, seeing him like that and seeing my dad push through it, keeping a smile on for my mom, my brother, and I. It made me realize the true meaning of love and friendship. When we were in that moment, it wasn’t really going through my mind, but now as I look back, I think why him, why someone who takes care of people now is battling with a sickness of their own, someone who has 3 kids and a loving wife why him. Why someone who spent their life helping others, why did he have to get sick, why him.

That day was a hard day for all of us, and as we parted and said our goodbyes, and drove away, it all seemed so unreal. The uncertainty we all faced we didn’t know if we would see each other again, that day is like a broken record that just keeps playing again and again, that and the picture from that Sunday of my dad and his best friend.

The door opened, and Dr. Jon and his wife, Linda, and son, Colton, came in. That afternoon as we played in the pool the laughter and happiness filled the house. That day was a good day. I can remember him in the pool laughing as Colton jumped in. The smile I had on my face as we all talked and laughed until we started crying. I remember my dad smiling as he and his best friend talked. And the most vivid memory of all to me, is the picture that was taken that day.

“Click” that one snapshot of life that one moment captured with the push of a button and a flash of a light. The picture that speaks a thousand words. My dad and Dr. Jon both so happy and lively as
they posed,arm around arm, both with huge smiles on their faces. I remember looking at how happy they both were and how that one picture makes me feel. And how even six months later, as I am writing this, that picture gives me hope.

Sometimes time goes slow, sometimes time goes fast, but time can also feel like lightyears away. Even though it was only two days later, I can’t stop thinking about how different Dr. Jon looked that day
compared to the last day we were there. I can still remember that day vividly, along with many, many, more memories of seeing Dr. Jon from the picture that is plastered in my mind to the video that
keeps replaying of us all in the pool. I just hope they aren’t the last. These are the memories and moments that I will never forget, the moments that shaped me into being who I am and how Dr. Jon
showed me to always live life to the fullest.

Writing this story is sad, but also happy in a way. In life I feel like people focus just on the bad things, but it is always important to find the light at the end of the tunnel, to find the good in things that are
tough. That is what I did with this story. Thinking about those days to come and the days that we had together are the things that keep all of us going.

I know I will never stop believing in Dr. Jon, and neither will he, he will always keep fighting until the day that there is no more cancer, until the day that my dad gets the phone call saying that his best friend is not sick anymore.

Life doesn’t come with an expiration. Life doesn’t come with a layout of how it is going to go. Life doesn’t come telling you what will happen. Seeing my dad’s best friend that day, seeing him still there fighting, that showed me the value of enjoying every moment. And most importantly, I learned to always surround yourself with ones you love, because you never know how long is left. I will always remember sunny days make those dark sky days easier.

Jon was a man of many accomplishments, his greatest being his family. He enjoyed the simple things. His family will miss him most while having coffee in the morning, kitchen table talks, cabin time, playing with the animals, fixing cars with the kids, telling bad dad jokes and we will always remember him taking time for outdoor adventures.
