Radial is a new model for mental healthcare.
One that simplifies every step of the care journey using a team-based, concierge-style approach. We handle it all with more purpose and less paperwork.
As we do, our goal is to get to the root of our system’s challenges, so you can do the same — healing your traumas, defining your path, and stepping confidently towards a more hopeful and meaningful future.
We believe in help that is actually helpful and use newer, more effective and rapidly acting treatments for conditions like depression, trauma and obsessive compulsive disorder.
- Licensed mental health clinicians
- Insurance coverage & payment assistance
- Dedicated clinical & support staff 7 days a week

Our core values
Act as a steward.
We stand on the shoulders of generations who fought for access to this care. We approach our work with responsibility and respect, honoring the legacy we’re part of and the people we serve.
Commit to transformation.
We believe transformation in the world starts with transformation in ourselves. We support and challenge each other to grow into the people this mission requires—with both kindness and skill.
Understand every patient.
We center our work around the experiences of those we serve. Many come to us shaped by past harm from people, systems, and care itself. We work to earn trust, share responsibility, and treat healing as a shared process.
Design for diversity.
Equity and access are core to our mission. We build systems with inclusion in mind, create space for honest dialogue, and seek out perspectives that challenge and expand our thinking.
