About Us

Accessible, efficient, affordable care... when you need it.

We are a Gastroenterology, Hepatology, and Therapeutic Endoscopy practice devoted to excellence in medical treatment using state-of-the-art technology & procedures.


A standard of excellence and personalized care enable us to provide the quality treatment & services that our patients deserve. We provide comprehensive evaluuations and follow strict standards on recommendations and therapies.


Safety, sterilization and infection control is of utmost importance to us. To protect our patients and ourselves, we strictly maintain sterilization and safety standards to protect you at all times.


As a practice, we are true believers that excellence in medical treatment is derived from both education and experience. We strive to keep current on the latest techniques and standards so we can provide our patients with the safest treatments, and the most optimal results.


We focus on thorough exams – checking your total health before performing and procedures. We feel that procedures are never routine, no matter how many hundreds of times we have performed such procedures. We never take for granted that you have placed a great deal of confidence in us. For this reason, a review of your medical history, your current health, your expectations for treatment and your motivations for electing our practice are all taken into consideration and discussed.


As your Gastroenterologist, Dr. Castillo wants you to be confident knowing that our team is highly trained and skilled. We pride ourselves in providing the care you need to optimize your health. To give you the best possible service and results, we are committed to continual education and learning. Dr. Castillo attends lectures, meetings, and conventions to stay informed of new techniques, the latest products, and the newest equipment that a modern practice can utilize to provide state-of-the-art procedures. Our physicians are members of the three major Gastroenterology associations: American Gastroenterological Association (AGA), American College of Gastroenterology (ACG), and American Society for Gastrointestinal Endoscopy (ASGE). This helps us to stay abreast of the changes and recommendations for our profession & specialty.


Building a foundation of trust by treating our patients as important individuals is vital to our success. We understand how uneasy some patients may feel about exams and treatment, and how we can make a difference in providing a life changing and emotionally positive experience. Our entire team is dedicated to providing you with excellent, personalized care and service to make your consultation and treatment as comfortable and pleasant as possible.

We thank you for allowing us to take care of your Gastrointestinal needs and look forward to serving you.
