Can a stutter be healed?

Can a stutter be healed? I am 24 years old, and have a genetic stutter /my mom and my maternal grandfather stutters as well/, and somehow it is getting worse for me. I am an HR, so I have to communicate with people on a daily basis and it gets really embarassing for me sometimes when I have a hard time getting a word out during interviews when I am the interviewer. Is it possible to stop stuttering ever? Is there hope?
