2026 MSO Conference & Trade Show

Once a year, MSO hosts an Annual Conference & Trade Show that brings together professionals from across the state. Over 350 people attend the event to earn CEUs for their professional certifications and licensures. In addition, we have a large trade show to see new products, visit with companies to learn about their technologies and our annual Roe-D-Hoe competition. Join us on January 19-21, 2026 at Margaritville Resort for this event!
