Meet the Doctor

Experienced physicians dedicated to your wellbeing

Dr. Alejandro Ruiz-Castaneda

Founder & Board-Certified Internal Medicine Physician

Hi, I’m Dr. Alejandro, a board-certified Internal Medicine physician focused on preventive care and helping patients manage their health.

I trained at HCA Florida Kendall Hospital, a Level 1 Trauma Center, gaining experience with acute and chronic conditions. My approach blends evidence-based medicine with lifestyle, nutrition, and sustainable habits to help you thrive.

Together with my wife, physician associate Christina, we founded RC Precision Health to offer personalized care through a direct care model, keeping our patient panel small to focus on you. I’m here to help you feel your best and live fully, one step at a time.

Patient stories

What our patients say

Very convenient. Clean office with lots of parking. Dr. Ruiz-Castaneda is very helpful, intelligent and efficient. Quick in and out office visit when I was sick. Very personalized. I will definitely go back.

Sherri DiMarco

Super easy to schedule. I loved my experience they took their time to understand my needs and provided excellent service. Parking was easy too!

Aileen Rodriguez

I am so glad I found Dr. Ruiz-Castaneda. I needed lab work and a second opinion. Scheduling an appointment was quick and easy and paying out of pocket for the bloodwork was actually cheaper than going through my insurance since I haven't met my deductible.
