We opened our Forest Lake office in 1991 in downtown Forest Lake just north of the intersection of Lake St. (Highway 61) and Broadway (Highway 2).  Our office is on the second floor.  We have had a longstanding strong relationship with Forest Lake Allina clinic doctors as well as local surgeons from Summit and St. Croix Orthopaedics. Our therapists also see many patients from other physicians and we also gladly see patients on self referrals.

Our therapists all deliver excellent orthopedic rehabilitation, and we provide specialty therapy services including occupational health through The Work Center, hand therapy, women’s health, aquatics, and biofeedback.

Our Forest Lake staff is very caring, friendly, and highly experienced. We have 5 highly skilled physical and occupational therapists and 1 physical therapist assistant.  Jan Olson, PT, OT, CHT; Sheila Maassen, PT; Tammy Kasprowicz, PT; and Trixie McConnell, PTA, each  have more than 10 years of clinical experience; they are joined by Andy Grupa, PT and Wendy Camp, OT.  Jan Olson has been with OSI for over 20 years and was one of the first certified hand therapists (CHT) in Minnesota.

Our Forest Lake location also provides occupational health services by Sheila Maasen, PT. For more information on our occupational health services click here: The Work Center
