Dr. Luke is originally from the Dayton area. He completed his undergraduate degree at The Ohio State University #GOBUCKS and earned his Doctorate in Physical Therapy from the University of Dayton where he received the distinction of “Overall Excellence in Academics, Clinical Performance, Scholarship, and Service.”
Dr. Luke’s passion for helping people move better has taken him across the country—from Lexington, KY to Miami, FL, Seattle, WA, and San Diego, CA—where he learned from top-tier physical therapists, trainers, and athletes. He’s worked with tactical, professional, and recreational athletes, gaining a well-rounded perspective on performance and injury recovery.
A lifelong athlete, Luke grew up playing baseball and basketball and now stays active through CrossFit, Hyrox, garage gym workouts with his wife and friends, jiu-jitsu at MPower Gym, and boxing with Coach Will at MPower! 🏋️🥊
His passion for physical therapy is rooted in personal experience—after an injury kept him out of the gym and away from the community he loved, he became even more motivated to help others stay healthy, active, and connected to what they enjoy. That drive continues to fuel the way he shows up for his clients and the Training Nation team today.
When he’s not in the clinic, Luke is spending time with his wife and three kids—Oakley, Harlow, and Lawson—hosting Harry Potter game nights, hanging out with friends, or doing anything outdoors: mowing, hiking, fishing, hunting, spikeball, soccer, golfing, snowboarding, or swimming.
Dr. April Einsfeld
PT, DPT

-Institute of Clinical Excellence (ICE) Fitness Athlete Completion
-Integrated Dry Needling Trained: Pain Management and Sports Rehabilitation
-Certified CPR
Originally from Fairfield, OH, Dr. April earned her undergraduate degree from Miami University before completing her Doctorate of Physical Therapy at Mount St. Joseph University. Her career has taken her across the country—from Nashville to Florida, Massachusetts, and Arizona—giving her a broad range of experience and a deep appreciation for helping people move well in every season of life.
Dr. April’s personal journey as a softball and basketball athlete shaped her approach to care. After dealing with sports injuries in high school, it was the mental and physical support of her physical therapist and athletic trainer that allowed her to finish her athletic career. That experience inspired her passion for physical therapy—not just to heal the body, but to support the whole person. Her compassionate nature and love for movement, health, and longevity continue to guide the way she works with each client.
Dr. April’s favorite way to stay active is to get outdoors🥾⛰️—whether it’s hiking, kayaking, paddleboarding, or outdoor workouts with friends and family. She’s always up for learning something new, and her latest hobbies include pickleball, golf, and Pilates.
Outside of the clinic, you’ll likely find Dr. April exploring a new National Park, checking out a new coffee shops, spending time with family—especially her nieces and nephews, going to concerts, or cheering on a Cincinnati sports team (even when they let her down)!

Certified CPR
Dr. Alicia is an Ohio native who earned her undergraduate degree from the University of Cincinnati (Bearcats fans welcome… Buckeyes, we can still be friends 😉) before completing her Doctorate of Physical Therapy at Mount St. Joseph University. Her passion for physical therapy comes from her love of movement, sports, fitness, and helping people get back to doing what they love. With experience in outpatient orthopedic and sports rehabilitation, Alicia enjoys working with everyone from competitive athletes to people just trying to get through daily life with less pain and more confidence.
Alicia believes physical therapy should be about more than just getting out of pain. It’s about building strength, improving confidence, and getting back to living life to the fullest. Whether she’s helping an athlete return to the field or helping someone get back to the gym, she loves finding creative ways to help people move better and reach their goals. She’s especially passionate about strength training and bodybuilding, but genuinely loves all things fitness and is always happy to talk training programs, proper technique, or why consistency in the gym matters (yes, that includes leg day! 💪).
When she’s not in the clinic, you can probably find Alicia lifting weights at the gym, playing sand volleyball, trying to save some stray animal, or spending time with friends and family. She loves staying active, challenging herself, and finding new ways to get stronger, both mentally and physically. Alicia is excited to be a part of the Training Nation team, bring some energy to the clinic, and help clients become stronger, move better, and get back to doing what they love!

Shannon’s preferred form of movement is hiking and Yoga🧘♀️, but inside the gym, you can find her playing with all sorts of mobility techniques, core exercises, and pushing + pulling the sled around. “Where I once had a dream to lift the heaviest barbell off the ground, now I focus on longevity, building muscle, and being able to play on the monkey bars with my little one.”
Outside of the clinic, you can find Shannon at a local coffee shop ☕️, making food for her friends, a park with her daughter, Zoey, or going on roadtrips to see live music. 🎶 She enjoys attending local SoundBaths and coaching people on a journey of self-discovery through breath work and cold-plunging. 🥶
