The doctor spent as much time as we needed discussing my father's needs and issues. He was very concerned and did not rush us.
Dr. Santiago is extraordinary for his level of practice and attention to his patients. He shows excellent clinical skill and works as much as possible with treating the patient and meeting the care-needs of his patients. I have first-hand knowledge of his excellence in patient care with not only my case but others and my observation is over years of time. He has an excellent set of clinical skills yet is very easy to discuss care plans with. He also does an excellent job of explaining treatment goals and his care analyses to the individual patient in a manner which is easily understood. Memorial Healthcare is fortunate to have him as a staff internal medicine doctor.
