We wanted to say an extra thank you to the founders of Medical Mission Adventures, Louie and Barb Rosado. Steering this organization since it's inception in 2010, Louie and Barb crafted a vision of what MMA could be and have devoted over a decade to make that a reality. 

Thank you Louie and Barb - we wouldn't be here without you!


A message from Louie and Barb Rosado from 2022

As COVID-19 brought to Medical Mission Adventures’ office a halt to the medical/dental/optical clinics, Louie and I talked about the future of MMA. We wanted to slow down, but we wanted MMA to continue.

In 2020, after traveling to Florida to care for Louie’s step-father for four months, two granddaughters joined us in Florida and traveled with us to Michigan where we spent time with our daughter and their aunt. Louie and I continued our road travel across the top of the United States to the State Parks in the South Dakota area. After seeing the vast, beautiful countryside of the United States, Louie agreed it would be a good move to live closer to our daughter and also be five hours from my elderly mother, my siblings, and relatives in Ontario, Canada. I could also return to the lush green environment of the Mid-West which I grew up in and missed for forty years while living in L.A.!

From the bottom of our hearts, we are so grateful for the many ways in which you have loved us, carried us, given us your time, labor, and finances, and shared tears with us in the many Medical Mission Adventures we have done together. Our hearts are warm and full when we think of how God has ministered to thousands of people on multiple continents through our work together.

We will frequent California to visit our son and friends, including our MMA volunteer friends! This leads to the future of MMA and the introduction of the new Medical Mission Adventures President, Dr. Evelyn Lo, MD!

Dr. Evelyn Lo, an emergency medicine doctor, approached us at the beginning of 2021, sharing her vision of making COVID-19 vaccinations available through clinics, and asked to use the covering of Medical Mission Adventure’s license and insurance for COVID-19 vaccination clinics.

Louie and I asked if Dr. Evelyn Lo and her husband, John, senior Pastor of Epicentre Church in Pasadena, would become the president of Medical Mission Adventures, taking on the task of running MMA. With Louie on the Advisory Board, we’d like to stay involved with MMA as volunteers.
