Meet Olena Zinshtein, RD, LDN

I find it rewarding to plant a seed of healthy eating where measurable outcomes come to life. I truly enjoy working with individuals to empower and build a strong nutritional foundation. In my practice, I incorporate useful workshops, seminars that are targeted services to help further individuals’ goals/needs, and inspire them to make healthy food choices. Helping clients integrate balanced meals in their daily routines thus making healthy eating a way of life. I enjoy practicing various activities from yoga to pilates and walking on the beach, staying active gives me constant energy and desire to nourish my body with functional foods. I love to cook, making this a family affair!
