About Valence
Your health, fully integrated — and personally guided.
Valence began with a simple observation: the people most disciplined about their work, training, and time often have the least clarity about their own physiology. We built a calm, precise way to change that.
The philosophy
Clarity is the luxury.
The promise of Valence isn’t a miracle or a shortcut — it’s a clear, honest read of where you actually stand, and a team to help you act on it. We sell measurement and clarity, not fear and not guarantees.
The work happens in Boston, operated by Back Bay Fit at 400 Commonwealth Ave, as a joint venture between two practitioners who care about doing this precisely.
Measured, not guessed
We start from data — real measurements of your body, your engine, and your blood — not assumptions.
Calm and unhurried
Premium doesn’t mean rushed. Your visit and your readout are given the time they deserve.
Complementary care
We work alongside your healthcare, never in place of it, and we’re clear about that line.
The team
A joint venture, by design.
Valence is a partnership between Back Bay Fit and MoveWithONYX — performance and rehabilitation, under one roof.
