What is Rock Steady Boxing SF?

Rock Steady Boxing, (RSB) the first and only boxing program of its kind in the country, was founded in Indianapolis in 2006 by former Marion County Prosecutor, Scott C. Newman, who is living with Parkinson’s. RSB gives people with Parkinson’s disease hope by improving their quality of life through a non-contact boxing based fitness curriculum.

Since 2006 RSB has grown to over 250 affiliates in the US and internationally.

RSB SF was the first Northern California affiliate and started classes in June 2014!

How do I start?

Nearly everyone with Parkinson’s disease can participate and receive benefit from Rock Steady Boxing. Some participants will require a cornerman (caretaker) to assist in each session.

We require all potential boxers to complete a 90 minute assessment with our RSB certified Coach Kim (Woolley) Voronin.

There is $100 fee for this assessment with no obligation to join BUT if you do join (and we hope you do!), you receive one free class to try it out.
