  • Biography


    My career in Internal Medicine has been very gratifying since I have been able to treat the whole family from adolescents to grandparents. I treat complex medical problems on a daily basis but at the same time I emphasize Wellness and Prevention as key elements to improve quality of life. It has been a real honor to serve my community with dedication and compassion .
