My goal is to create a seamless, supportive partnership where you feel fully guided, confident, and empowered in achieving results that are both transformative and enduring.

Food has always been at the center of my journey. I began in Culinary Arts in 2002, drawn to the creativity and connection food brings, and by 2007 expanded that passion into nutrition, focusing on how what we eat shapes our health and well-being. When people are faced with making life-changing health choices, they need an ally who can clear up the confusion and encourage them toward change. Specializing in nutrition education and disease management, I have over 18 years of experience assessing needs and designing plans to teach others about the role of food and nutrients in the body and their effect on total wellness. I understand that no single approach is “perfect” for everyone, so using my skills in Culinary Arts, Nutrition Education, and Chronic Disease Management, I work to find solutions for individual nutrition and lifestyle goals. As a nutrition educator, I’ve seen how knowledge empowers people to move past confusion, make confident choices, and take meaningful steps toward better health. My patients will focus on the tools to transform their well-being and create lasting change. I can't wait to meet you!

I'll help you see that 1% of progress will help you become even better than you were yesterday and even closer to the person you want to become.

I help clients enjoy an approach to wellness and health that creates nutritious and joyous eating habits to provide you with tools and strategies to help you create a healthy, positive, confident, and sustainable approach to food, nutrition, and your own body with healthy self-care,banishing joyless patterns of eating, and working with where you are right now and helping you on this path to a better mind/body well-being.

I am a Registered Dietitian-Nutritionist and Certified Specialist in Sports Dietetics (CSSD) with over 4 years of counseling experience. I have a PhD in Nutrition Sciences, a Master's degree in Health Promotion, and a Bachelor's degree in Dietetics. I specialize in working with clients who are looking to increase performance in and out of the gym, athletes, weight change, and anyone who is looking to improve their overall health and nutrition. Personally, I have Type 1 Diabetes, won collegiate nationals in cheerleading, and currently compete as a competitive crossfitter.

I'm a Registered Dietitian and Board Certified Specialist in Sports Dietetics with over 8 years of experience working with college and professional athletes and 3 years of working as a personal trainer. I specialise in using nutrition to improve athletic performance, change body composition, and optimize overall fitness. Make no mistake, I'm not a dietitian just for the elite athlete. I became a personal trainer after completing my schooling because I believe every active person deserves access to elite-level nutrition to supplement their efforts so they can stop guessing at how to build muscle and lose fat, but be on their way to making it happen with my guidance.

My approach as a dietitian is rooted in openness, respect, and collaboration. You are the expert on your own body and life, and I am here to support—not dictate—your nutrition journey. I practice person-centered care and use motivational interviewing to ensure our work in sessions reflects on your values, preferences, and lived experiences. Together, we will explore strategies that align with your nutritional needs and health goals, always with compassion for the challenges you’re facing. Progress isn’t always linear—sometimes it’s about celebrating small, meaningful steps forward. I recognize that changing lifestyle habits takes time and effort, and I firmly believe that nourishing eating habits should retain joy and satisfaction. I offer evidence-based, practical guidance that replaces diet culture, food fads, and misinformation. Everybody deserves a positive, maintainable approach to eating and feeling well.

I’m a Registered Dietitian with a diverse background in hospital, community, and sports nutrition. I’ve provided patient care in both a large urban hospital and a rural Wisconsin healthcare system, giving me experience with a wide range of medical and cultural needs. In the community, I’ve supported large school districts in San Diego and smaller ones in rural Wisconsin to improve menus and nutrition education. I also have sports nutrition experience working with Division I football athletes on performance fueling. Alongside these roles, I’ve gained extensive one-on-one counseling experience, both in person and via telehealth, helping individuals navigate weight health, disease prevention, and long-term lifestyle change.

I possess an innate ability to simplify the process of weight loss and dietary changes in a way that clients can easily wrap their heads around, making the task much less overwhelming. I see each client as the individual person that they are, and I individualize my approach accordingly. I provide clients with nutrition counseling that improves their relationship with food, and expands their understanding of nutrition education. I currently specialize in working with clients who have weight management goals and aspire to improve their overall health and wellness.
