Where will my massage or bodywork session take place?

At the office.
Must I be completely undressed?

No- If face down and I work on the back/neck/shoulders, I only need the top off.  If full body, then down to skivies and under the sheet.
Will the practitioner be present when I disrobe?

No- your door is closed while you get ready.
Will I be covered during the session?

There is a sheet if necessary.
What parts of my body will be massaged?

Depends on what you want worked on.
What will the massage or bodywork feel like?

Slightly intense and maybe up to your pain level.
Are there different kinds of massage and bodywork?

I mainly focus on the deep tissue massage.
What should I do during the massage or bodywork session?

Go with the flow- relax as much as possible.
How will I feel after the massage or bodywork session?

You will feel you have been worked on.  I always tell them to give 2-3 days for the massage effects to settle down.
What are the benefits of massage and bodywork?

Muscles are more relaxed and a general feeling of more calmness.
Are there any medical conditions that would make massage or bodywork inadvisable?

Yes- but the client usually tells me about their situation before hand.
