Just suggestions from a parent not a pro:
Keep the marketing one as its own line - play up how you increased awareness, attendance - as it will show the business side. If you can site specifics - like tickets sales increased X amount etc that would make it stronger. Made X $ if you sold tickets and funds went to assist X. Added another show due to demand or developed an online campaign, poster contest, moved ticket sales to online platform etc - I know you didn’t do all these things, but what did you do in this position to help awareness and get people in the seats?
Can you group your lead choreographer, assistant director and stage manager into one spot with descriptions specific to each.
Make sure to state strong facts about what you did as the President over 2 years.
