Dr. Gastelum is extremely thorough and truly cares for his patients. I would recommend his service to my loved ones. He takes time with his patients and is always educating them. Top rated physician and I know plenty of them

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.

For my particular medical condition, this provider offered current prescription information about dealing with medical condition in order to consider trying another solution and it worked. I'm grateful even though the portion the insurance covers for the Rx leave a rather large co-pay. Although I found another source through the manufacturer that was supported in documentation from this provider and I'm elated with the outcome.

Comment about MA: when scheduling an appointment for a patient, please don’t comment on how busy the doctors schedule is and that we (the office/doctor) are doing me (the patient) a favor by squeezing me into his busy schedule.
