Meet Our Staff


Kwame Asamoah, MD

I’m a native of California who relocated to the Austin area in 2007.  I attended UCLA for medical school then completed my emergency medicine residency at the University of New Mexico in Albuquerque.  I’ve had the pleasure of working in numerous emergency departments throughout Texas throughout the years. I was motivated to start ExpressMD after observing a growing trend of minor medical emergencies presenting to the ER.  I knew that there was a more convenient and cost-effective way for these patients to get the care that was needed.  In addition to running Express MD Urgent Care, I continue to work in a few emergency rooms. In my spare time, I enjoy travelling with my wife and 2 daughters.  I also enjoy biking, hiking, and cooking.

I am originally from Michigan, but Texas has been home for 12 years. You can usually find me out on the field cheering on my kids in whatever sport they are in, or planted in front of the TV watching our favorites the Houston Astros, Michigan Wolverines,  Dallas Cowboys or Seattle Seahawks.
