So far it’s been great but FYI it’s not Mark’s program. It’s a program that a married couple came up with who are doctors with many years of research. It gives me feedback knowing how many short phonations you produce in your speech. Short phonations don’t necessarily mean you’re stuttering but there’s certain words that don’t produce normal flow of speech. My speech pattern has completely changed over these past two weeks. I don’t talk the same and the whole idea of the program is to make you speak more from your throat if that makes sense. Mark is a good guy so be sure to ask all the questions you want to know and he will tell you what he thinks. I don’t know your situation but this program is pretty expensive. It can cost anywhere from 4500-5000 USD but Mark also accepts CareCredit so you can pay monthly. If you have anymore questions feel free to DM me.
