Lori Winslow, Pilates Instructor
tel: 415.823.1352
email: lori@flow-sf.com

Lori is certified through the Pilates Sports Center and a member of the Pilates Method Alliance. She graduated from the University of Connecticut with a degree in Speech Language Pathology and moved to San Francisco in 2001.

Lori was first introduced to Pilates in 2005, rehabilitating a herniated disc injury that halted her active lifestyle. Pilates exercises aided in not only her successful recovery but also allowed her to identify the imbalances in other areas of her body, and address them as well. She left her corporate career (and too much time sitting at a desk hunched over a computer) to immerse herself in Pilates' highly effective conditioning practice and share its powerful mind and body transformation possibilities with others.

Knowing first hand how a body in pain can affect every part of one's life, Lori wants to use that awareness to help people experience the benefits that come from having the balanced and strong body that Pilates can offer. Whether you are taking Pilates to supplement your own athletic ability, recover from an injury/surgery or seeking a healthier and more balanced life, her goal is for you to leave a session with her feeling stronger, taller and livelier than before.
