A message from the President

Dear Visitors,

Welcome to the official website of the Hispanic American Medical Association of Houston (HAMAH). As a president of this esteemed organization, it is my privilege to extend a warm greeting and share with you some valuable insights about our association.

I would like to start by thanking the members and the HAMAH board for allowing me the honor of the position of president.  I have been a member for about 5 years now and have had the privilege of working with some excellent leaders within the association including Dr.Rafael Fonseca, Dr. Kathrym España & Dr. Roy Riascos. I have really appreciated helped these great leaders do their work. You give a great example of leadership, and motivation to continue moving forward with the association.

I firmly believe in advocating for the rights and equal opportunity for all healthcare professionals, regardless of their country of origin and recognize the immense contributions that international medical graduates, especially those of Latino origin, bring to the healthcare field.

I must acknowledge that the pandemic has been a challenging time for the healthcare sector and organization like HAMAH. While the pandemic has brought immense challenges, it has also demonstrated the resilience and unity of our community it has inspired me to redouble our efforts, find innovative solutions, and advocates for our members and Hispanic community.

HAMAH is a dedicated community of healthcare professionals committed to improve health and well-being of the Hispanic population in the Houston area, provide professional development , foster networking and mentor medical trainees.

One of the most inspiring programs is the scholarships , HAMAH strive to create a supportive environment where aspiring healthcare professionals can thrive , regardless of their background or financial circumstances.

HAMAH has tremendous history, but historical significance alone will not sustain the association indefinitely. Membership is the key to continuing our mission in the support of Hispanic physicians to maintain the highest level of quality health care to our community and support young leaders in medicine. Together, we can break barriers, bridge gaps, and build a healthier future for the Hispanic community.

Thank you for your interest in the Hispanic American Medical Association of Houston. We invite you to explore our website further to learn more about our initiatives, events, and membership opportunities. Feel free to reach out to us with any questions or inquiries.
