Our Therapists

Donald L. Olsen, EdD, PT, OCS

Inspired to help people achieve a healthy and active lifestyle, Donald Olsen began his advanced education by earning a Bachelor of Science degree from Eastern Michigan University.

He then achieved a Physical Therapy degree from Columbia University, followed by an M. Master of Science from Emory University and a Doctoral Degree in Education from United States Sports Academy.

A life-long learner, he has also acquired certification as an American Physical Therapy Association Board-certified Orthopedic Specialist and is Level 2 Certified in Balance and Vestibular.

He gathered extensive work experience in a variety of settings. He started his current practice in 1985 in Milwaukee Wisconsin (Northshore Physical Therapy) and in 1992 he opened a clinic in Sanibel Florida, both as private physical therapy practices.

He is also on the Faculty at the United States Sports Academy.

When he is not working, he enjoys volunteering with community activities and church work, participating in sports, especially running, biking and hiking, coaching with Team Speed, spending time with his family and dogs, giving talks about health in the community and travelling and teaching internationally.

Thomas Charles Casey, MPT

Physical Therapist Thomas Charles Casey, who received his Masters of Physical Therapy from Marquette University in 1996, brought a broad range of experience with him when he joined FYZICAL Therapy & Balance Centers Northshore in 2013.

He has a background of working in private medical clinics as well as in outpatient physical therapy rehabilitation at the Children’s Hospital of Wisconsin.

He is a specialist in manual physical therapy techniques as taught by The Institute of Physical ART with a special interest in movement patterns, posture, gait and exercise.

His passion for sports and physical games ignited his interest to become a physical therapist.

As a physical therapist, he takes a special joy and satisfaction in breaking movement, function and physical ability into its elements and modifying them to allow his patients to gain renewed ability and greater ease of movement.

When he is not working, he enjoys spending time with his seven grandchildren and teaching them new things. He also likes fly fishing, canoeing, and rowing his boat. When there is snow, he enjoys cross country skiing and completed the Birkebeiner this year. He also likes to play the piano in the privacy of his home. He has gradually moved away from competitive sports and now enjoys the long and “healing” sports.

He sees patients in both the Cedarburg and Thiensville clinics.

Ann, who joined the company in 1991, became an occupational therapist to enable people to regain their previous level of function in areas of self-care, leisure and work activities when it has been altered due to illness or injury.
