    Dr. Scouros is an avid reader, and as a proud Greek American, can always recommend the best souvlaki in town.

  • Dr. Shiraz Dhanani, Cardiology

    As a Board Certified Cardiologist, Dr. Shiraz Dhanani enjoyed a busy practice in the Spring Branch area for nearly thirty one years whereby he had the privilege of diagnosing and treating cardiovascular diseases in thousands of patients with confidence and joy.
