While I will occasionally book one lesson in-person on my phone, I much prefer to book a
package of lessons via email. I use gmail and when we are going back-and-forth arranging a time please stay within the email thread. Don't reply with a new email. I teach 7 days a week and normally have a 10:30, 12:00, 1:30, 4:30, and 6:00 slots available. When I have open slots I am trying to fill, I will offer those same slots to different clients. The first person to get back to me can have that available slot.
