We were there for our 3 month check up. HE went over my blood work with us in detail. Gave us pointers on what to avoid in our diet. We are very pleased with the care we receive from Dr. Gastelum. He is thorough and explains everything to us.

The Doctors are knowledgeable and compassionate, helping the patients see how we can manage ourselves through a healthier lifestyle. This is a busy office and it is sometimes difficult for a new patient to get an appointment in a timely manner. However, once you are an established patient it is easier to get in to see a doctor as needed.
