Marissa, a dedicated Registered Dietitian, is passionate about helping others heal their relationship with food. Inspired by her own health journey, she brings empathy, understanding, and practical tools to guide clients in quieting “food noise” and finding sustainable balance. With a whole-person, individualized approach, she simplifies nutrition, making structure and routine attainable. Rejecting diet culture, she empowers clients to nourish their bodies, supporting digestion, metabolism, mental health, skin, and hormones.
Marissa specializes in weight management, disordered eating, behavior modification, gut health, anti-inflammatory meal planning, GI disorders, food sensitivities, autoimmune disorders, thyroid disorders, PCOS, type 2 diabetes, prediabetes, hypertension, high cholesterol, kidney disease, liver disease, and malnutrition or unintentional weight loss.
Marissa is currently accepting new patients, and would love to help you on your health and wellness journey. Appointments are available virtually, and are covered by insurance. Complimentary 15 minute phone consultations are available for individuals who would like to learn more and find out if they are a good fit for her treatment approach.
