The Team

Coached every session.

The single biggest difference between Cornerstone and a globo gym is the coaching. You'll know our coaches by name, and they'll know yours.

Brandon Killin, coach at Cornerstone Fitness

Brandon Killin

CF-L2, CrossFit Kettlebell, USAW Level 1

Brandon Killin didn't come to Cornerstone planning to stay. He started as a college kid looking for a fun job — mostly to help out a friend — and somewhere in those first few months, he found he couldn't turn away from it. What began as a side gig became the thing he knew he wanted to build a career around.

What keeps him here is the people. Brandon loves helping someone become their own hero, and says there's no better feeling than watching a person shatter a belief they were sure was permanent. He'll happily work with the hard chargers and the pushers, but his real joy is helping someone who's been injured get their life back. He refuses to let anyone settle for "this is just how it is now."

That's why he's all in on Cornerstone: every day, he gets to help lead a community of people toward things they never thought possible.

It is a shame for a person to grow old without seeing the beauty and strength of which their body is capable. — Socrates
Hannah Bowling, coach at Cornerstone Fitness

Hannah Bowling

CF-L1, WAG Certification

Hannah Bowling found her way to Cornerstone the way a lot of people do — by needing something for herself. After her two boys were born, she picked up running for the alone time, and it took: three marathons later, she knew she wanted to add weight training to the mix. She'd been doing personal training with a group of women and went looking for something closer to home, and that search landed her at Cornerstone. She trained here for about two years before taking the leap into coaching, and she hasn't looked back since.

What drives her is meeting people where they are. Hannah loves working across the whole picture — fitness, nutrition, and the everyday habits underneath both — and helping people set the kind of goals that move them toward the best version of themselves. She'll work with anyone willing to help themselves, and she has a particular soft spot for teens: they come in open to learning, and watching them grow into their confidence in the gym is one of her favorite things.

She's all in on Cornerstone because it's the place that's always been there for her, even in the stretches when she wasn't there for herself. As life has pulled in different directions, those four walls have stayed put — and she knows this is her happy place.

Life is too short to choose anything that doesn't light a fire inside your heart.
Beth Masters, coach at Cornerstone Fitness

Beth Masters

CrossFit® Level 1 Trainer; WAG Certified Nutrition Coach; Certified Menopause Coaching Specialist

Beth Masters found Cornerstone after her family's move from Baltimore to Ohio in June 2019. She dropped into a few local gyms looking for the same sense of community she'd loved back in Maryland, and she knew almost immediately — the first class she took at Cornerstone told her she'd found her new gym home.

Coaching, for Beth, brings together everything she cares about. It draws on her background in education and her passions for health and longevity, for helping others, and for sharing her own autoimmune health journey — what she's learned along the way, now turned into something she can pass on so others can feel their best too. Above all, she loves that she gets to teach: breaking down movements and skills, planning scaling options, mapping out how to approach a workout, the same way she once planned lessons for the classroom. What makes it matter to her is the reach — the chance to shape a member's health in their hour at the gym, and to watch it flow into the rest of their life, whether that shows up as more strength, a steadier mindset, better nutrition, more confidence, or simply more capacity for the people and demands around them.

Her favorite people to coach are women over 40 who've hit the point where what used to work for their fitness and nutrition just doesn't anymore. They're ready to make real changes — to build strength, find their energy again, feel more confident, and understand their hormones, nutrition, and habits — and what they need is guidance, education, and someone in their corner holding them accountable. That's exactly the work Beth loves most.

She's all in on Cornerstone because it surrounds her with like-minded people all working, in their own way, to keep improving across every area of health and longevity.

In every single day, in every walk of life, ordinary people do extraordinary things. Ordinary people accomplish extraordinary things. — Coach Valvano
Stacey Hodgett, coach at Cornerstone Fitness

Stacey Hodgett

M.Ed., Secondary Education, Xavier University; Mat Pilates and Pilates Apparatus Certification, PhysicalMind Institute; WAG Certified Nutrition Coach; NASM Women's Fitness Specialist

Stacey Hodgett's love of fitness and movement started in childhood, playing multiple sports and dancing. Around 2000 she found Pilates, and it quickly became more than a practice — she trained for her initial Mat Certification, completed her Apparatus Instruction in 2008, and began teaching the Pilates Method to clients while living in Massachusetts. In 2016 she joined Cornerstone as a member, looking for new ways to challenge herself physically. Along the way she started programming and coaching the Sweat class, and eventually moved into coaching CF classes too.

What she's passionate about is helping people feel better and understand how to move their bodies well. The fundamentals of Pilates, she'll tell you, translate into everything — even breathing and sitting — and can improve how a person performs in any part of their life. The muscles of the core support, suspend, and protect the spine, and Stacey loves teaching people how to reach those deep muscles to build real strength and stability while easing the pain or discomfort they've been carrying.

Her favorite work is with clients who've dealt with chronic pain or injury, helping them become pain-free or regain function. She knows that road firsthand — knee pain as a teenager from imbalanced muscular structure, and neck pain from a herniation after the birth of her son — so she understands what chronic pain does to the body and to a person's mental and emotional state. Helping others prevent or minimize that is, to her, beyond fulfilling.

She's all in on Cornerstone because this community is everything: the way everyone shows up in support of one another, she says, is amazing.

Change happens through movement and movement heals. — Joseph Pilates
Ashley Jerue, coach at Cornerstone Fitness

Ashley Jerue

CrossFit L2, WAG Nutrition, CPR

Ashley Jerue likes to believe that Cornerstone acquired her previous gym just to hire her. Whatever the real story, she landed here — and she fits.

Her passion is simple: she wants to help people learn to love what their body can do for them. Her favorite clients are the ones who show up open to new — and sometimes scary — ways of moving and growing, because that's where the good stuff happens.

She's all in on Cornerstone because, here, health is understood as so much more than just a workout.

Stop telling yourself that the grass is greener on the other side. Screw grass. Dandelions fix the soil that they're in and grow in defiance of those who would thwart them. Be a dandelion.
Courtney Hopkins, coach at Cornerstone Fitness

Courtney Hopkins

B.S. in Exercise Science (working toward a Doctorate in Physical Therapy), USAW L1, CF-L1

Courtney Hopkins started at Cornerstone at 16, and now, at 22, she's been here long enough to call it home. She'd just stepped away from gymnastics after ten years and needed something new. She'd heard about CrossFit, and Cornerstone happened to be close by — but she had no idea she was walking into a place she'd come to call home, with members who'd become family. The community, she'll tell you, is really like nothing else.

She coaches out of a simple conviction: we should always keep moving in some way, whatever our age or limitations, because there's always something you can do. Part of what drew her to coaching is that starting something new is the hardest part — so she loves helping people find their footing in the gym and steer clear of the mistakes she made early on. And she adores watching members light up over a new milestone, whether it's strength, conditioning, or gymnastics. Nothing is too small to celebrate.

Her favorite people to work with are kids of all ages and anyone with a real drive to get stronger. With her younger athletes, she loves teaching them the ins and outs of the gym while walking alongside them through their elementary, middle, and high school years. With the strength-seekers, she loves teaching the process and the movement patterns behind the work.

She's all in on Cornerstone because you won't find another community like this one — people who'll help you in your journey both in and out of the gym, and celebrate every win along the way.

Challenges are what make life interesting; overcoming them is what makes life meaningful. — Joshua J. Marine
Anthony Rabas, coach at Cornerstone Fitness

Anthony Rabas

CF-L1

Anthony Rabas came to Cornerstone after a year and a half of P90X, looking for something that would challenge him and push him outside his comfort zone. He'd seen the CrossFit Games on TV and had always been curious, so he looked up gyms in the area — and immediately fell in love with the community and the people.

He coaches because he wants to help people change their lives the way he was helped when he first walked in. He saw how significantly his own life changed for the better, and he wanted to share that with others. Watching people get better, have fun, and push themselves is deeply rewarding to him — and there's nothing better, he says, than seeing someone accomplish a goal they've been chasing.

His favorite clients are the ones who want to be better and aren't afraid to ask for help. To Anthony, the humility and strength it takes to admit you're not perfect is more inspiring than raw natural talent, and he'll go out of his way — staying late, spending the extra time — for anyone who works hard and leaves their ego at the door.

He's all in on Cornerstone because it changed his life. The person who walked through the doors in 2020 is nowhere near the person he is today: a better athlete, brother, son, coach, leader, and friend than ever before — all thanks to a community that pushes him to be better every single day.

As iron sharpens iron, so one man sharpens another.
Lyndsey Townsend, coach at Cornerstone Fitness

Lyndsey Townsend

CrossFit Gymnastics

Lyndsey Townsend joined Cornerstone when she moved to Ohio in 2013. She'd started CrossFit about a year earlier and figured that if she could find a gym, she'd at least have a way into meeting new people. Cornerstone was the first gym she walked into, and she never looked back. She was welcomed in and brought into the fold immediately, and while things looked a lot different back then — the gym was literally tucked into a shopping center — it's only gotten better every day since. She's not only met her closest friends here; she met her now-husband in this community. It's truly her home away from home.

She coaches because she loves guiding people toward the things they set out to do — whether that's perfecting a lift, working up the courage for a first handstand, or even strategizing the best road-trip route across the country. Deeply analytical and endlessly enthusiastic, she spent a lifetime as an athlete learning how to move and overcome obstacles, and she loves showing others they can do it too. (It helps that she was a cheerleader for years — she's loud, and she wants to cheer you on. Perfect for coaching.)

Her favorite people to help are pregnant and postpartum women. Since becoming a mom in 2020, she saw firsthand how much misleading information exists about training while pregnant, and how few resources there are to support moms afterward. She got a little obsessed with learning everything she could to support her own recovery — and found a real passion for helping others through that season of life, whether newly pregnant or many years postpartum.

She's all in on Cornerstone because her life would not be the same without the community, support, and friendships she's built within these walls. There's nowhere like it.

You are stronger than you think you are.
Erin Rairden, coach at Cornerstone Fitness

Erin Rairden

B.S. in Health Appraisal and Enhancement, Miami University; Associate of Nursing, Miami University; Certified Pediatric RN; HYROX Group Certification; Keiser Group Cycle Certification; CPR Certified

Erin Rairden likes to say fate brought her to Cornerstone in 2021. Her new CS fitness family welcomed her with open arms, and since then she's had the pleasure of making plenty of new friends who share her passion for movement and fitness.

She coaches from a place of personal conviction. Erin loves to feel strong and fit, and that's what drives her to encourage others to start moving and see how their bodies can change for the better. We're only given one body, she believes, and we should treat it as well as we can — and anyone and everyone can benefit from movement.

She honestly loves sharing her passion and knowledge with anyone willing to listen. As a pediatric RN, she sees firsthand how much our younger population needs to move. She also loves helping the aging population realize they can stay independent longer with the right functional fitness programming. And as an endurance athlete, she has a soft spot for anyone who wants to push their body to its limit. Truly, she loves helping all ages and all fitness levels.

She's all in on Cornerstone because she believes that with the right fitness family, anything is possible.

To give anything less than your best is to sacrifice the gift. — Steve Prefontaine
Jen Rockwern, coach at Cornerstone Fitness

Jen Rockwern

HYROX Certification; Board-Certified Women's Health Nurse Practitioner; Board-Certified Nurse Midwife

Jen Rockwern has built her life's work around supporting women through every stage of life. As a board-certified women's health nurse practitioner and a certified nurse midwife, she spends her days outside the gym stressing the importance of nutrition and movement to her patients — and inside the gym, she puts that same medical knowledge to work helping clients reach their physical goals, whether they're staying fit through pregnancy, recovering postpartum, or navigating the body changes of midlife.

As a mom of four, Jen also believes that healthy habits are formed early, which is why she loves coaching in Cornerstone's youth programs. She's committed to the well-being of every member here — and she looks forward to seeing you around the gym.
