Hi, I’m Dr. Alejandro Ruiz-Castaneda. I’m a board-certified Internal Medicine physician with a passion for preventive care and helping patients take control of their health. I completed my residency at HCA Florida Kendall Hospital, a Level 1 Trauma Center, where I gained hands-on experience managing everything from acute illness to chronic disease.

My approach combines evidence-based medicine with a strong focus on lifestyle-nutrition, movement, and sustainable habits—so you can thrive, not just get by.

Unlike many traditional insurance-based practices, I wanted to create an environment that allows me to spend more time on quality care and relationship building. With my wife, physician associate, Christina, I created RC Precision Health. Through our direct care model, we are able to maintain a smaller patient panel, allowing us to put the focus on you, the patient.

In my spare time, I enjoy an active lifestyle with Christina and our son. I’m here to help you feel your best and live fully, one step at a time.
