About Greenfield Physical Therapy

Greenfield Physical Therapy & Sports Medicine, LLC was established in February of 2014 by clinic owner and licensed physical therapist, Amy Greenfield, PT. Greenfield has 19 years of experience in physical therapy, with 15 of those years in private practice. Her undergraduate degree from UW-LaCrosse in Athletic Training has allowed her to be able to provide extensive care of area high school, collegiate, and some professional athletes over the course of her career. She has also been trained in a multitude of industrial rehabilitation specialties through the Occupro system since 2006 and has provided care both onsite and in clinic to a variety of area businesses over the years. Her staff is now all trained in Occupro Systems making their clinic a specialist in industrial rehabilitation in the area.

Prior to owning, Greenfield was employed through a private practice group from 2006 through July of 2013 with them she had spearheaded, opened, and managed a clinic in Spooner which opened in July of 2007, and later a clinic in Hayward which opened in March of 2010. With a desire to grow things herself, she went on to open her own practice in 2014 in Spooner where she lives with her family and continues to foster and build relationships within the community, as well as with the physicians that she’s worked with throughout the entirety of her career. She and her team have recently had the ability to expand into Hayward, WI as well with opening their second location in July of 2021.

The Greenfield PT team prides themselves on being a welcoming environment that provides a high quality of care whether it is in clinic, at your home, or workplace, we will take care of YOU, your insurance needs, and your physical well being from start to finish.
