I am a native of Arizona, married and have one son. I have been a Respiratory Therapist since 1994. I have worked with sleep patience since 2003. The reason I love to work with patients that have obstructive sleep apnea is because I feel it is rewarding to me because I get to see them when they are sleep deprived and I can have them as patients for years. I get to see the progression of their lives changing from being treated. I think my best quality is I really listen to what my patients are saying. I feel that really helps me to help them and others that have the same issues. I learn new things everyday even though I have been in the field for years there is always something I learn.
I have personally been involved with the success of CPAP for many years with my family. Since I can remember I had always wanted be a sleep tech. I had been going to school for a few years and it was time to decide what I wanted to do when I grew up. The PSG program was very enticing so I took the leap and here I am. Working graveyards with some of the most amazing people that call themselves “sleep techs”.

Sleep is a vital part of our daily lives
Yet, 70 million Americans suffer from a sleep disorder and approximately 95 percent of those affected remain undiagnosed and untreated. Sleep deprivation may cause short (or even long-term) health risks (i.e. heart disease, heart attack, stroke, depression and memory loss).
