About Prosperous PKU

Prosperous PKU centers around wellness. But not wellness from a traditional, commercial sense in that you have to be or do something specific to be well, like lose weight or eat an organic diet. My name is Sarah Hope Marshall, and I created Prosperous PKU out of my lifelong battle with rare disease. Wellness as defined by conventional health beauty standards was never an option for me. However, my accomplishments have far exceeded what doctors told my parents would be possible when I was diagnosed at 11 days old. Prosperous PKU aims to pass along the lessons I learned about what it means to live well.


Wellness means self-awareness, discipline, stewarding what you have, living life with purpose, advocating for yourself and others, communicating well, internal leadership, and appreciating the diversity in this world. Wellness is a state of being, not a specific body weight. Wellness requires understanding your own values and making decisions from a place of authenticity. It is a state of prospering, which means to succeed in what you set out to achieve, as defined by your own internal goals, values, and visions.
