Get in contact with the National Stuttering’s Association (NSA). There telephone number is in the United States +1 800 937 8888. Ask for Tammy Flores. If Ms Flores is not in the office, then ask for Melissa. Ms Flores is the National Director for the NSA. I am going to include their website address as well. I do hope that the moderators do not remove this post because of the web link or the telephone number. The NSA’s web address is: https://www.westutter.com On the site you will find information about submission for research studies. Good luck.
