Meet The Leadership Team
Years ago, Kaci, Joe, and Michelle sat down with Kaci’s father and shared a dream of creating a place where people could access exceptional rehabilitation, movement, and wellness services under one roof. Although Kaci’s father is no longer with us, his vision and legacy continue to inspire what has become The Fort.
Today, River Bend Physical Therapy and Apex Physical Therapy have come together under one name—River Bend Physical Therapy—uniting our team while continuing to serve patients throughout the Flathead Valley. Our main clinic is located at The Fort in Bigfork, with additional satellite clinics in South Kalispell as well as at the Montana Athletic Club in Bigfork.
The Fort was created to be more than a physical therapy clinic. It is a place where health, movement, and community come together. Home to River Bend Physical Therapy, pilates, yoga, personal training, and Hayline Coffee, The Fort reflects our commitment to helping people move well, stay active, and live healthier lives. We are honored to continue serving the Flathead Valley and look forward to welcoming you to our new home.
