About Us

Dr. Liza Klein

I am Dr. Liza Klein, dentist, bacteriologist, founder and CEO of GOODBREATH LABS, LLC. I have performed scientific research and clinical treatments in the field of halitosis for the better part of 2 decades.

I have successfully treated thousands of halitosis patients with my proprietary ozone-based oral health products and protocol. My journey in the field of halitosis therapy began as a personal crusade early in my career as a dentist when I decided to find viable solutions for my father’s condition.

At the core of GBL’s success is the belief that we can and will improve people’s lives through the effective management of their breath in order for them to lead productive and confident lives within their communities.
