“I never want them to go through an injury that’s going to be long-lasting or regretting, pushing through something or doing something wrong. They trust me that I’m not going to put them in harm’s way,” Rennalls said. “When I say they can go, they can go and when I say pull back, they know there are reasons for it. Of course, they might fight me on it because they are competitive and want to play their sport, but they know I’m here for them.”
“Karl has been someone who the entire team has felt supported by on and off the field for the three years he has worked with us,” senior forward Tia Dupont said. “He is someone who you genuinely know is looking out for our best interest and just wants to see us thrive while we are at UM. Karl is extremely selfless and dedicates himself to keeping all of us healthy and happy. Whether it’s coming in early to do rehab with us or staying late to help with recovery, Karl would always be willing to do it with no complaints. For me personally, Karl has been one of the most impactful people I’ve met through UM athletics.”
Along with the words shared by Miami’s senior captain in the fall, junior defender Sierra Frey explained how Karl’s willingness to answer questions while she rehabbed from a leg injury that shortened the 2020 fall campaign for her was invaluable.
“Karl is an absolutely amazing human being. He is so dedicated to his job, often having to work from super early in the morning to super late at night. He is constantly researching ways to prevent and treat different injuries the team may have, and types up individual plans for each of us for every day while we are in the training room,” Frey said. “He has been the team’s biggest supporter and works tirelessly day in and day out to make all of us better. Karl is such a kind-hearted person and is always there to brighten our days. I would honestly say one of my favorite parts about going to practice each day is being able to see Karl and talk to him in the training room.
“During my time here at Miami, I have had multiple injuries so I have been able to spend a lot of time with Karl,” Frey added. “This past season was extremely tough due to my injury preventing me from playing this fall. However, Karl has been so helpful in getting me back to my full health so that I will be able to play this spring. Every day I would come in and Karl would be very transparent about my rehab plan and was so willing to answer any questions I had about moving forward. Never once was I ever made to feel scared about my injury. There were some days that were obviously mentally harder than others because no athlete wants to be sitting out for the season, but Karl was always there to listen to me and was extremely understanding of how I felt and did what he could to make me feel better. Although I wasn’t able to be training on the field during practices, I knew I would continue to get better on the sideline with him. I can genuinely say that the team as a whole is so appreciative for everything he has done for this program because we know we would not be the players we are today without him.”
With the long hours in place, the opportunity to watch the athletes grow as individuals is what it all comes down to for Rennalls.
“We as athletic trainers talk about ow we work in a thankless job,” Rennalls said. “We are expected to get our athletes back; that’s just part of the job.”
So, when a player returns to the field, scores a goal, or makes the next step in their career, those are the moments that cannot be described in words.
One of those instances took place in the 2020 fall finale against Duke when redshirt freshman Jackie Koerwitz tallied her first career goal just 14 months after tearing her right medial patellofemoral ligament (MPFL).
“Jackie Koerwitz last season overcame a traumatic injury and through hard-work not only does she return this past fall but then she scores a goal and you just look back and smile,” Rennalls said. “Also, even since graduating, Lauren Markwith was training and pulled her quad, so she reached out to me about what to do. This is because I have built this trust with them, where Lo and Kristina Fisher still ask me questions. So, when I get them back on the field playing the sport they love, it’s just a full validation of all the hours I put in here. The sheets that I write every day, the rehabs I put them through, it just all feels worth it. Athletes like Dejah [Cason], whom I still have a great relationship with, come back and tell me how thankful they are for not just helping them as an athlete, but helping them as a person too. That feeling is just irreplaceable.”
This trust is even seen in players who have yet to take the field for the Hurricanes.
Entering the summer hoping to make an immediate impact for Miami, freshman midfielder Hannah Dawbarn suffered a season-ending ACL injury prior to making the trek from her hometown in High Wycombe, England.
“While I’ve been injured Karl has been a huge support: driving me around in the days after my surgery, making me feel at home with his ‘English’ accent and always checking in on me. He’s always been so positive and has celebrated the small gains I’ve been making in my recovery, which makes the process so much easier,” Dawbarn said. “While sitting on the sidelines watching practice I would bombard Karl with loads of questions about my injury and other injuries, and he would always patiently give me detailed answers which I have been able to apply in both my rehab and my classes. Seeing how he works has also allowed me to see how everything I’ve been learning in class about athletic training is actually applied in real life. He’s definitely someone I look up to and has made my first semester here a great experience.”
Now in his 14th year in South Florida and eighth year as an athletic trainer, Rennalls is exactly where he belongs.
“The U to me is home. I couldn’t imagine being anywhere else. I love this school so much. My family loves this school so much. My mom will buy everything orange and green,” Rennalls said. “This is just home and this is family. I look up to Vinny as one of my biggest mentors and Dr. Harriell as well. I get to work with Julia Rapicavoli, whom I went to school with here. I say I’m from New York and I am a New Yorker at heart, but whenever I think of Miami, I think of wearing the orange and green. You can’t beat being in the middle of December wearing shorts and a t-shirt and having the opportunity to sit on the beach. That’s the great thing about this city, you can find anything here. I couldn’t imagine being anywhere else and I’d love to be here as long as I can. I look forward to sending my kids here.”
