Dr. Castillo is a Staff Physician specializing in Internal Medicine. He is bilingual in English and Spanish and graduated from Universidad Iberoamericana, in Santo Domingo, Dominican Republic. He also completed his residency at Saint Barnabas Hospital in the Bronx, NY, where he was recognized as Intern of the Year. Castillo entered a career in healthcare to help treat those in need. What he loves most about his profession is building relationships and helping patients improve their lives and overall health. He especially appreciates that at CenterWell, both the patient and physician are allowed the time to solve problems together. For Dr. Castillo, ensuring patient satisfaction means listening to patients and allowing them to voice their grievances no matter how small they may seem. It also means forming a team where patients can make informed decisions that are in line with their beliefs and wishes. Dr. Castillo defines the “right” relationship with patients as one where both the physician and patient have complete transparency and one where decisions are made taking into account all of the patient’s needs. Also, it’s where the patient is treated with respect as his philosophy of care is, “The patient always comes first.” In his time off, Dr. Castillo’s hobbies include horology, motorsports, Spanish cinema and baseball.
