Paula Dougherty was born and raised in the Catskill Mountain region of Upstate New York. She graduated from the Culinary Institute of America at Hyde Park, New York in 1983. Upon graduation, Paula worked with the famed chef, Albert Kumin, whose many prestigious accomplishments included work as the pastry chef for the White House. Paula spent approximately twenty years in the food industry, cooking, baking, teaching health and nutrition and eventually owning her own restaurant in New Mexico. When her son was born however, she decided it was time to hang up her apron and change to a career path that would provide her with more time to raise her child. Combining her love for children with her administrative skills, Paula began work as an education administrator. For Paula, The Healdsburg School has not only been a wonderful place to work, but it was also an amazing educational experience for her son Mackenzie, who graduated in 2010.

In her spare time, Paula enjoys cooking, mountain biking and traveling with her family. Her dream is to write a novel which she hopes to get started on very soon
