Good morning! Thanks for calling Apex Financial. I can help you schedule a portfolio review with Mark. Which day works best for you?
ME
Hi! Do you have anything open this Thursday afternoon around 2:00 PM?
Let me check Mark's schedule... Thursday at 2:00 PM is taken, but I have an opening at 2:30 PM or 4:00 PM. Would either of those work?
ME
2:30 PM sounds great.
Perfect! I've reserved Thursday at 2:30 PM. I'm texting a confirmation and calendar link to this number right now. Have a great day!
