Meet Nan


Nan Kosydar Dreves, Professional Health Horizons has been a registered

dental hygienist for over 20 years. She has an extensive knowledge of occupational

health, safety, and compliance issues for dental professionals and stays up to

date on current and new practices so she can share with your staff.


Nan has a passion for what she does and it shows! She brings energy and excitement

to her seminars and trainings so they are not only educational, they are enjoyable too!


Nan still stays close to the dental industry as the Office Manager and Practice

Consultant for Matthews Family Dental in Whitehall, WI, Mork Dental in Winona, MN
and Cochrane, WI and Complete Family Dentistry in Waukesha, WI. As a registered

hygienist, she also still works with patients on a regular basis. In her free time, she

enjoys spending time with her teenage son, Jacob, plus spinning, yoga, travel, Cassie

(her shih tzu-bischon) and presenting seminars on dry topics with humor. “Carpe Diem”

(Seize the Day) is her mantra in life.


"Nan makes a difficult subject enjoyable and easy to understand."
