I will be single-handedly running my mother's clinic over her 2-week vacation. What would be my official job title, for resume's sake?

**Edit**: I am normally the **President** of the clinic -analyzing performance and implementing solutions (including coding custom software, running analytics, etc.)

This is an **OT/PT/SLP** clinic (i.e. **Occupational, Physical, and Speech Language Pathology Therapy**.)
