Founding Members


Denisse Rojas

Denisse Rojas Marquez envisions a health care system where no individual is excluded. Growing up as an undocumented immigrant, she and her family had limited health care options and as a result, they would often delay treatment for illnesses and use free or subsidized health care. Through these difficult experiences, Denisse was inspired to become a doctor in underserved immigrant communities that advocates for all patients and is a leader in shaping health care policies. Denisse was 10 months old when she and her family left Mexico for the United States. As a resident of Fremont, California, her family found new opportunities that enabled Denisse and her two siblings to attend college. Her path, however, had many roadblocks. Due to her status, Denisse was ineligible for financial aid and was often discouraged that no career counselor could offer guidance on her aspirations. Moreover, Denisse was painfully separated from family members who, as a result of stalled policies on immigration, left for Canada. Denisse remained steadfast in her aspirations and co-founded a national organization called Pre-Health Dreamers (PHD) to provide advising, resources and advocacy for other undocumented youth like herself. In just a few years, PHD has reached 800 members in 42 states. Through Denisse’s leadership, the organization co-sponsored legislation to allow CA licensing boards to award professional licenses to undocumented professionals and engaged in institutional advocacy with other academic groups. As a result, over 50 medical schools will consider undocumented students for admission.

In 2015, Denisse proudly became the first undocumented student to attend the Icahn School of Medicine at Mount Sinai where she is working towards her MD and in 2016, she was awarded the Soros Fellowship. Denisse will devote herself to a life of service through clinical care, research, and policy to ensure that quality health care is accessible to all immigrants.


New Latthivongskorn

New emigrated from Thailand to the United States’ San Francisco Bay Area when he was nine years old and is now a recent graduate from the University of California-Berkeley, with a bachelor’s degree in Molecular and Cellular Biology. Throughout college, he funded his education with part-time jobs and private scholarships while staying involved in groups such as the Thai Student Association, Resident Hall Assembly, and the AB540 Coalition on campus. Off-campus, he served as a first co-chair of ASPIRE (Asian Students Promoting Immigrant Rights through Education) at Asian Law Caucus, where he advocated and fought for the passage of the federal and the CA DREAM Act of recent years. As a New American Scholar of Educators for Fair Consideration, a non-profit organization supporting students in higher education, he shares his personal immigration experience to portray a different side of “DREAMers”. Most importantly, he continues to speak out as an Asian undocumented youth to increase visibility of API communities in immigration reform, reframe the public’s perception, and create a community for other API undocumented youth.

As an aspiring medical doctor who also hopes to pursue a Master’s degree in Public Health, New seeks to remedy the barriers that low-income and immigrant families of America face in accessing healthcare. His time volunteering with the homeless through the Suitcase Clinic and with Oakland’s low-income communities as a Healthy Ambassador of Mentoring in Medicine & Science exposed him to the stories of different communities, but also the struggles shared by all of them. His experience in scientific research includes two years at the School of Public Health at Cal studying the essential genes of the murine cytomegalovirus (MCMV) and, most recently, a summer research fellowship in the Department of Physiology and Biophysics at Weill Cornell Medical College examining the kidney’s functions. New aims to become a physician who practices medicine through a public health lens, using primary care, research, and policy to shape health for the individual and the community. He has helped start Pre-Health Dreamers in hopes of alleviating the barriers he has faced for future undocumented students pursuing their dreams in the health and sciences.


Angel Ku

Angel Ku is a Mexican immigrant who grew up in northern California. He attended San Francisco State University where he studied Chemistry and Molecular Biology. On campus he aided in establishing SF State’s Undocumented student organization, IDEAS where he lead efforts to host teach-ins and conferences to inform prospective students and staff on how to support undocumented students in higher education.

As an undergraduate he worked with Dr. Marquez-Magaña at SF State’s Health Equity Research Lab to study barriers to recruitment of minority patients onto clinical trials. He is currently a Ph.D. candidate at the University of California, San Francisco’s department of Bioengineering and Therapeutic Sciences where he is investigating how cancers become resistant to targeted therapies. These efforts will aid in developing new treatment strategies that will be more effective and safer for patients. In the future Angel seeks to establish his own academic lab where merge his passion for health equity and systems biology to continue to improve the lives of cancer patients.

It was both his passion for advocacy and science that lead Angel to co-found Pre-Health Dreamers (PHD). During his journey, the prospect of becoming a principal investigator seemed at times hopeless due to his immigration status; however, it was through building a community of support that allowed Angel to sustain his motivation to continue on his journey. Angel attributes his success to his family, friends and mentors who always motivated and pushed Angel to develop into a better advocate and scientist.
