Dr. Katashia Partee Kendrick is a Clinical Pharmacist, Integrative Health Practitioner, Certified Sound Healer, and the founder of Dr. Katashia Wellness Kollective.

Her vision is deeply personal. After years of navigating infertility, stage 3 endometriosis, and multiple surgeries for fibroids—including a hysterectomy—she transformed her pain into purpose. These experiences became the foundation of her mission:to educate, inspire, and empower women and couples to advocate for their health and embrace holistic wellness.

With nearly two decades of clinical expertise, Dr. Katashia blends evidence-based medicine with integrative practices, offering a unique approach that addresses the body, mind, and soul. She is passionate about helping women and couples to prepare their bodies for pregnancy, supporting them through hormone transitions, and guiding them to find peace and restoration through sound therapy meditation.

At the heart of her work is community. The Wellness Kollective fosters a space where women are not only seen and heard but also equipped with strategies, resources, and practices that help them thrive. Whether through intimate sound bath experiences, one-on-one coaching, or educational workshops, Dr. Katashia champions women’s wellness with compassion, expertise, and authenticity.
