Jessica Davis

Owner - Lead Phlebotomist

I’ve been a certified Phlebotomist and Medical Assistant since 2010, with years of experience in lab processes, specimen handling, and shipping, all while ensuring that everything meets the highest standards. I specialize in hormone health, fitness tracking, and weight loss. I offer mobile phlebotomy and custom lab panels designed to make healthcare more accessible and comfortable for busy people. My goal is to make sure you feel supported, respected, and cared for, especially when it comes to something as personal as your health. I’m all about making the lab experience easier and more convenient, offering online booking, and maintaining confidentiality every step of the way. As a black-owned, female-owned business, I’m committed to providing top-quality care, with a focus on hormone wellness, right at your door.
