A husband-and-wife duo who wanted to help you unlock your healthiest self.
Between us, decades of experience in Kinesiology, strength & conditioning, nursing, and Division-1 athletics. We opened KB Fitness because we wanted a studio we'd actually want to train in — and a community that treats every member like a person, not a punch card.
Kurtis.
Kurtis holds a Master's in Kinesiology & Rehabilitation and is a Certified Strength and Conditioning Specialist (CSCS) — the gold standard credential in the industry. He's also the published author of Finally Fix Your Back Pain.
His specialty is working with clients other trainers don't know what to do with: older adults, post-surgical clients, people with chronic back pain, and athletes looking to return to sport without re-injury. If you've been told to "just stretch more" or "listen to your body" by a trainer who didn't have an answer, Kurtis does.

- M.S. in Kinesiology & Rehabilitation
- Certified Strength & Conditioning Specialist (CSCS)

Specialty
Older adults (seniors), training clients around injuries, post-rehabilitation strengthening, general fitness, & sport-specific athletic performance.
Corinna.
Corinna is a Certified Personal Trainer, a former Division-1 athlete, and a Registered Nurse — a rare combination that makes her especially effective with women navigating pregnancy, postpartum recovery, and major life transitions.
Her athletic background means she knows what serious training feels like. Her nursing background means she knows how the body actually responds to stress, injury, and recovery. Both show up in every session.

I've completed about 20 sessions with Coach Aaron at KB Fitness and have made awesome progress over the past two months. I'm noticeably stronger and more confident, thanks to Aaron's personalized, purposeful, and challenging workouts. He's attentive, knowledgeable, and incredibly encouraging.
Huge thanks to Kurt for creating such an amazing atmosphere, and especially to my coach Aaron for keeping every session engaging, challenging, and tailored to my goals. It's a place that makes you actually look forward to working out.
