The Team - East Cobb County

From the beginning, TSG has been dedicated to providing patients with the highest level of therapy services available. Realizing that our success would be measured by the level of dedication and professionalism of the people we employ, we decided to build an internal team rather than contracting outside therapists. All TSG therapists are employees of the company, holding a master’s degree and licensed by the State of Georgia. By investing in our own employees, we’ve built a team of experienced therapists simply unmatched in the field.
