“I have been a patient of Dr. Ton-That for almost 20 years, back when he was at Medical City Dallas. He’s always been a friendly, genuine and caring Dr. Very knowledgeable in his profession. ”
Ellis R.March 14, 2026
“The doctor took his time to explain everything I had concerns about, and I didn't feel as though he was rushing to his next patient. I felt as though he got on my level and gave me the option to make an individual improvement rather than pushing medication on me.”
Cassandra H.November 26, 2025
About Dr. Quynh Ton-That
Dr. Ton-That was born in Viet Nam, but his family decided to escape from the communist regime for a better life in 1978 when he was 9. They settled in Wichita, KS, where he grew up and graduated as valedictorian from Maize High School. He received his college education from Wichita State University and earned his Doctor of Medicine degree from the University of Kansas School of Medicine.
After finishing his residency in Internal Medicine at Baylor University Medical Center at Dallas, he started his medical practice as a hospitalist at Baylor Garland Medical Center in 1999, eventually transitioning to an outpatient practice at Dallas Medical Specialists in 2004. Hoping to continue providing care to the surrounding communities, Dr. Ton-That relocated his practice to Addison Internal Medicine in 2013.
Dr. Ton-That has been married since 2001 and has three wonderful sons. Besides taking care of his children, he enjoys art, golf, tennis, and traveling. Through all the years of his training and practice, he is guided by one simple principle: ?Humility and gratitude - being a doctor is an opportunity for me to give back the kindness and compassion that people have given me and my family.?
