Meet the Doctors
Dr. Im, Dr. Su and Dr. Nahm all worked together prior to launching their own business together 10 years ago. They have all worked and trained in level-one trauma centers, and Sacred Heart Emergency Center was born out of their observation that there was a need in this community that wasn’t being met. Working in the hospital, it was difficult to provide comprehensive care for the patient. They wanted the chance to have a conversation with their patients and treat the whole patient, not just the symptoms. The dedicated doctors and staff are here to get you back on your feet and feeling better quickly.
Dr. Mark Im was born and raised in Houston, Texas. Born right here at Memorial City Hospital, he grew up in the Spring Branch area and is currently a resident here in Hedwig Village. He attended St. Jerome School and Strake Jesuit for high school. Dr. Im trained at UT Houston Medical Center and finished his Emergency Medicine residency at Suny Stony Brook in New York. On his time off, he likes fishing and golfing; however, most of his free time is spent with his daughter and Jisu, his wife. Jisu is a part-time violin teacher and faculty at Tallowood Baptist Church orchestra. Their daughter, Leia, is 5 years old and takes up a lot of his time!
Dr. Wesley Nahm is a true Houstonian, born and raised. He attended Texas A&M University and studied medicine at University of Texas Health Science center in San Antonio. There he met his wife, Dr. Laura Mendoza. They both attended residency in Ohio and moved to Houston to raise their two children. They have lived in the Memorial area for over 17 years. You can spot Dr. Nahm running in the Memorial area with his Doberman.
Dr. Di Su lived on three different continents before age 12. He attended Bellaire High School in Houston. After graduating from Duke University, he received his medical education and training at Medical College of Virginia and the University of Rochester. He spends his free time with his wife and two children, and he is also an avid collector and hunter.
