Dr. Harold Katz, DDS, opened the first California Breath Clinic to treat patients with mild and chronic halitosis in 1994. A graduate of the UCLA School of Dentistry in 1975, and recipient of a degree in Bacteriology in 1971, Dr. Katz researched the real cause of bad breath and developed a way to eliminate it.

It started when Dr. Katz’ 13 year old daughter developed chronic halitosis. Dr. Katz combined his dentistry experience and bacteriology research to discover the cause. As he discovered, the bacteria in her mouth was causing bad breath… not the food she was eating. Dr. Katz perfected a solution to the problem and within minutes of using what is now called “TheraBreath,” her bad breath was gone.

Dr. Katz is a veteran radio and television guest. He has been featured on 20/20, The Today Show, Good Morning America, Fox After Breakfast, WOR, KFYI, WCBS and hundreds more, and his articles have appeared in numerous newspapers and magazines including the New York Times, LA Times, Harpers, Glamour and Mademoiselle.
