Built on consistency.
Owned by family.
Evolution Fitness is a long-standing fitness facility built on consistency, hard work, and community. Today, under new ownership by siblings Jill and Chuck Miscavage, we remain committed to honoring that foundation while continuing to grow and evolve for the members who make this gym what it is.
A new chapter on an established foundation.
Evolution Fitness has been part of the local fitness community for years, helping members build strength, confidence, and healthier lifestyles.
Today, the gym is owned and operated by siblings Jill Miscavage and Chuck Miscavage, who stepped into ownership with a shared commitment to preserve what makes this facility special while continuing to move it forward.
This is not a complete restart. It's a continuation.
Jill
Miscavage.
Jill brings a deep personal connection to the facility. A member since 2013, her experience inside the gym gives her a strong understanding of the community and culture that makes this place unique.
Partnering with her brother, Jill is focused on creating a supportive, motivating environment where every member has the opportunity to succeed.
Chuck
Miscavage.
Chuck is proud to carry forward the legacy of a long-established facility while helping shape its next chapter. While new to gym ownership, he brings a strong commitment to creating a welcoming, supportive environment where members of all levels can thrive.
Alongside his sister, Chuck is dedicated to building a space where hard work, consistency, and community come together.
