Just did guest interview via Skype for a social work graduate class on the pros and cons of using telehealth in rural settings. I did a tally and found I have/have had clients I have worked with remotely (i.e., via phone, vid, chat) in 13 states, and 5 countries:

USA:

Arizona, California, Colorado, Illinois, Kentucky, Michigan, Missouri, New York, Tennessee, Texas, Utah, Virginia.

INTERNATIONAL:

Afghanistan, Canada (Alberta and Ontario), England, Mexico, Norway

Telehealth (or remote therapy as I call it) is a fascinating advancement in my field and I'm glad to have been an early adopter. Amazing how technology is helping bring more help to more people, give clients greater choice over their care instead of just "taking what they can get."

Someday I'll post the interview to further illustrate the pros and cons, some considerations on how to do it effectively, etc... or make it into an FAQ for clients.

Note: This map should show Canada highlighted (I've worked with clients in two provinces there).
