The charges were filed after Howard allegedly used the Chamber credit card for a number of personal expenses.
In the response, Gary Mishler, acting board president said, "As soon as this matter came to light, we took immediate action, including his separation from the organization.
"Since then, the Board has conducted a thorough review of our financial practices and internal controls, and we have implemented changes to strengthen oversight and prevent this from happening again."
Howard's arraignment is scheduled for 9 a.m. October 7 in Jasper County Circuit Court in Joplin.
