Richard Codding

It was evident early on that Richard had a green thumb and a passion for agriculture. By his fifth birthday, he was tending a productive berry patch in Glasgow, DE. Harvesting the berries at their peak ripeness, he’d load them into his Radio Flyer wagon and sell them door to door.  A lover of travel, Richard embarked on a summer’s long cross-country road trip after he graduated from the University of Delaware with a degree in Business Administration. His travels eventually brought him to Nevada County where he became enchanted with the culture, landscape, and climate. He quickly decided to return to plant some roots. He currently enjoys coaching youth athletics and his enthusiasm for Sierra Harvest’s mission is palpable.  He is eagerly anticipating the day when all students in Nevada County have access to scratch-cooked meals featuring fresh, local ingredients.

Tiana Rockwell, President

Tiana is a functional nutritional therapy practitioner with a private practice in Nevada County. She believes that a nutrient-rich, whole food diet can help people find optimal health and thrive! She moved to Nevada County in 2007 and started a private dental practice with her husband, Sean Rockwell. Through her many years in the dental field, she was able to see firsthand how poor nutrition can affect the body. The mouth is the gateway to the whole system and it is not uncommon to see disease start in the mouth before other areas of the body. She loves the work that Sierra Harvest is doing to help make local, organic, nutrient-rich foods accessible to everyone.

She fell in love with Nevada County after completing a yoga training here many years ago, and moved to town in 2021 to get closer to the mountains and community. She joined Sierra Harvest because of her interest in sustainable and local food sourcing and desire to give back.
