Originally born in London, Jack grew up in Sussex from the age of 8 in Heathfield. By the age of 14, however, he had attracted interest from Wimbledon FC and made the move to their academy.
“It was a wake-up call and a bit of a shock to see the difference in level. I also found that all of a sudden I was going from playing with my friends, and people that I grew up with, to playing with people that I didn't know at all.
“I was also having to travel up on the train. It’d take me to two-and-a-half-hours, and I wasn’t really socialising with those guys at all, because then it was straight back on the train and home.
“I definitely found that hard because I wasn’t really playing with my friends anymore, but that was also a good thing. It was a learning curve. You then realise how competitive the sport is. I was there for two years from under-14 to under-16 and then I didn't get offered a scholarship.
“I really wanted to sign for Brighton, but they had two really good goalkeepers in my age group, Richard Martin and John Sullivan. I still keep in touch with John a little bit, but they were both good goalkeepers.
When Jack was let go by Wimbledon, he joined Burgess Hill Town until under-17s level when he signed for Lewes. He broke into the first-team that were promoted to the National League Premier Division before making a big decision.
“I went out to do a scholarship in the USA. I intended on being there for four years it was in South Carolina and I had some injury issues.
“Anyone who knows anything about the college system in America will know, it's intense. You play like 12-15 games in about two and a half, three months. Then you have the play-offs and if you get injuries, you can miss pretty much the whole season.
“But aside from the injuries, I found the thing I didn’t enjoy was the pressure of games, I just loved the training. I think at that point, when I was out in America, is when I decided, I don't think a professional playing career is for me.
“However, I wanted to stay in the game, and actually, before coaching, I wanted to be a therapist or a physio.”
Many people who realise their limits in football will continue to play at whatever level they can. Something Jack goes along with: “A lot of people, nearly all of my friends just continued wanting to play even if it was non-league. I think that's one of the things that's really helped me in my career making a clean break.”
Jack, on the other hand, wanted to be involved with football at the highest level possible and if that wasn’t going to be from playing, he was going to find another way.
“I came back to England and went to the University of Worcester to study Sports Therapy. During that time, I realised I just want to be out in the grass, I want to be out in the field. With the therapy side of things, there was so much time spent being inside and being in treatment rooms so after one year, I switched to do sports coaching.
“Once I'd started that, I then I did my FA Level 1 and 2 as well as the goalkeeping qualifications and at university I was about 35 minutes away from West Brom. I had a friend who was working in their community arm and he mentioned to me that the academy was looking for an assistant goalkeeper coach and asked if I’d be interested in doing that.
“That was my foot in the door, and that's where I really started to take coaching and goalkeeper coaching very seriously.
“I was massively lucky to have such a great mentor at West Brom, called Mark Naylor who is now the head Academy Goalkeeper Coach at Aston Villa. He just had so much passion for it. He lived and breathed goalkeeping and he just took me under his wing, he saw potential in me and taught me how to be a coach.
“After the first six months to a year of working with him, I knew this is the path I'm on, head down and I'm throwing everything at this."
