Two tiny holes called the Eustachian tubes. These connect their ears (tympanic membranes) to their mouth. In males, 2 holes are in the vocal sac. In the back of the mouth are 2 holes: the glotiss and the gullet.
Private practice rates. If you are working in a supervised private practice, on the other hand, you will likely make more per hour. For example, as an LPC intern, I had a sliding scale that ranged from $30 to $75 per session. I have also seen interns charge $10 per session and more than $100 per session. Please remember that published rates, even on a sliding scale, does not mean that people are pulling those fees in at all, or with every client.
$500.00 to $1,500.00 per visit / by session. If it is a local company and a small group I can charge less. If it is a true Training Seminar there are printing costs etc., so my rates get bumped up to meet those needs. It also depends of the number of people in attendance and the difficulty of the project.
