About Me

I practice in obstetrics and gynecology, specializing in high-risk pregnancy. This includes an emphasis on diabetes in pregnancy. My focus on maternal fetal medicine involves treating these and other medical complications that can happen during pregnancy.

My goal is to inform my patients about various aspects of their care. I am also an advocate for birth options such as vaginal delivery after cesarean section. I believe in providing patients with comprehensive care while listening and providing answers to questions that may arise.

The people at The Ohio State University Wexner Medical Center are among the many things I appreciate about working here. I am blessed to work with a team of talented and committed individuals who put patients first.

When I'm not at work, I like to relax with my family, attend Ohio State football games and travel. I run five times per week, but I am getting a bit slower as I grow older!

He was very nice and funny.

Dr. Landon was very rude as was the observer from China. She stood between the dr. and I and I talked to their backs while the looked at the computer. Dr. Landon was not a positive experience for me and my husband on an exciting yet stressful day of seeing our baby for the first time. I will continue to see another dr.

Dr. Landon is fantastic and I love how he takes time to discuss the visit each time.
