Hello everyone, my name is marc jung. I am Tustin and I have been working as a hairdresser in Southern California for about 20 years. I learned a three-day course smp about two years ago because I had no hair or lost my hair due to a wound or illness, but I didn't think it was enough to get a procedure on your scalp, but I got to know Jeff and I'm going to learn it properly. I expect it to be of great help not only in learning technology, but also in business philosophy, marketing, and further education. I hope we can do well together until the end. Thank you.
