About Karen Steffer, M.D.

Why did you choose to specialize in Gastroenterology?

I have a family history of colon cancer and colon polyps and as a gastroenterologist I am able to prevent colon cancer on a daily basis. Additionally, while GI diseases are extremely common, each patient’s symptoms and treatment course are individualized; working with patients to find a successful treatment plan is extremely rewarding.

Do you have a specialty of interest within GI?

As a female gastroenterologist I have am particularly aware and accustom to treating women with gastrointestinal diseases. I also treat general hepatology conditions such as chronic viral hepatitis, Autoimmune hepatitis (AIH), Primary Biliary Cholangitis (PBC), and steatohepatitis (“fatty liver disease”).

Where did you study?

Undergraduate: Baylor University, Medical School: University of Texas Medical Branch, Internal Medicine Residency and training in Gastroenterology and Hepatology: Baylor University Medical Center.

What certifications do you hold?

Board Certified in Internal Medicine, Gastroenterology and Hepatology.

What do you and your family enjoy doing in your spare time?

Life is busy with my husband and three small children. We enjoy traveling (when possible), outdoor sports and spending time with our family and friends in the area.

Do you have any special honors or recognition in your medical career that you would like to share?

Honor society (AOA) in my medical school class. Resident of the Year during my Internal Medicine Residency.

Please list your professional affiliations.

Texas Society of Gastroenterology and Endoscopy, American College of Gastroenterology and American Gastroenterological Association.


Dr. Steffer is awesome. She is personable and very easy to talk to and she actually listens. Her and her entire staff were on point, making the entire experience seamless and I definitely recommend her.

Dr. Steffer is a caring and patient physician. She scheduled my procedure at a convenient time for me. Unfortunately, a member of my family has Covid-19 so we will need to reschedule in a few weeks. The staff at TDDC and Lone Star Endoscopy have been helpful and professional.

As a first time patient with Dr. Steffer and her staff I am still overjoyed at the level of excellence and kindness shown from the time I pulled up to make the phone call to check in, to the time I left with my instructions. In such a dim season the kindness shown was Music To My Soul. Thank You Dr. Steffer and Staff. You Inspired Me!

Dr. Steffer is incredibly kind and patient. She really took the time to listen to me. Undiagnosed medical issues cause a lot of emotional turmoil on top of the physical problems, and she put me at ease and took my explanations seriously.

Dr Karen Steffer is a very good Doctor. She actually takes time to explain her examination to you and answers all your questions you have. The staff at Lone Star Endoscopy is great and makes you feel as comfortable as possible. They really care about your well-being and go out of their way to make you feel good that you on at their facility. This was my fourth Colonoscopy and endoscopy, but first one at Lone Star and rate it above the other 3 I have had.
