The promotion of these two key staff members to senior leadership positions is part of the firm’s strategic business plan for continued growth in its St. Louis and Ohio/Kentucky/Indiana (OKI) markets. IMPACT Strategies celebrated a record year in 2022 with more than $110 million in completed projects throughout five midwestern states.
