What Our Patients Say

Real reviews from real patients who trust Lake Nona Medical Services with their care.

Don't let the old school front facade of this building fool you. The services from the moment you step in are friendly and respectful. Dr. Catherine Arevalo is professional, knowledgeable and explains every detail on tests. You won't find a better General Doctor around.

Adrienne

I'm very impressed with this place. It's so hard to find a doctor that listens to you. I'm so happy with Dr. Arevalo. She was efficient. She solved all my concerns without telling me to see a specialist. I was done within 1 hour.

Morgana S.

A full team of angels. They worked hard to get my son to a safe blood pressure and way of life. I truly believe that they have saved my son. New medication and a game plan was given right away. The love for the patient is the number one standard.
