Hello, I'm Courtney Birtcher. My interest in health and fitness is more than a hobby; it's a way of life I love to share, encouraging others to find their balance and vitality. Fashion and beauty are also close to my heart, and I enjoy offering practical style advice and makeup tips to help people feel their best. Away from the screen, I'm often reading a novel or enjoying the outdoors with my three dogs. I have experience in the fashion industry, notably as a published model, which enriches the content I create, bringing professional insights with personal passion. I cherish my Ohio roots but, I embrace the chance to connect with diverse audiences online. My goal is to deliver content that informs and inspires. I aim to contribute to my community through various platforms.
