Emilia Hart

Oklahoma Public Health Association Board of Directors. She runs Smart Bites Oklahoma, a wellness and nutrition coaching business in Norman. She is bookkeeping and administrative professional for Urban Agrarian, a local food hub dedicated to connecting consumers with locally grown and produced food.

She spent eight years in communications before obtaining her nutrition certificate and launching her wellness coaching business. Throughout her time coaching nutrition and wellness clients, she became increasingly aware of the health disparities that plague Oklahomans, particularly regarding access to high quality food and healthcare. This sparked her interest in community nutrition and public health, and inspired her to begin a master's program for nutrition and dietetics.

She received her BS in Agricultural Communications from Oklahoma State University 
in 2007 and her nutrition coaching certificate in 2014 from the Nutritional Therapy.

She loves to serve her community, connecting women with health services regardless of health insurance or ability to pay.
