Our Physicians

Dr. Dawn Sumrall moved to Southwest Mississippi to start her practice in 1992.  Since then she has delivered over 5,000 Pike Countians!  She retired from the baby business in 2017 and has since dedicated her practice to Women’s Health Care along with Nurse Practitioners Kappi Rushing, Diane Lazarus Van, and Kasie Holmes.

Dr. Sumrall was born in New Orleans, Louisiana and graduated high school in Lewisville, Texas.  She went to medical school at University of Texas Health Science Center in Houston and finished her residency at University of Mississippi Medical Center in Jackson in 1992.  She is licensed by the Mississippi and Texas State Boards of Medical Licensure.  She is Board Certified by the American Board of Obstetrics and Gynecology and participates in yearly board recertification.

Dr. Sumrall has been married to Hiram, a Mississippi native, for almost 40 years.  They live on their farm in Liberty, raising beef cattle and horses.  Her son Austin, and wife Tresse live in Biloxi and have a son, Hiram Oliver born in 2015.  They are chef/owners of White Pillars Restaurant in Biloxi.  Her daughter Laura, and son-in-law Carl Muntean, raise show cattle in Iola, Texas and both also work for Texas A&M University.  They have a daughter, Harper Elliott, born in 2019.

Dr. Sumrall is an avid gardener and recently earned her Master Gardener Certificate from Mississippi State University.  She is a life member of the McComb Garden Club and a member of the “Bunko Babes” for 30 years.  She enjoys cooking and is collaborating on a cookbook with chef/son Austin.  Her favorite job is being Grammie to Ollie and Harper!


Kappi is a 2000 graduate of The University of Southern Mississippi where she earned her Bachelor of Science in Nursing.  She began her nursing career at King’s Daughters Medical Center working in ICU and the Surgery Department.  In the summer of 2013, Kappi returned to her hometown of Natchez and worked at Riverpark Ambulatory Surgery Center while attending graduate school.

In 2006 Kappi graduated from Alcorn State University with her Master’s of Science in Nursing and started working as a Nurse Practitioner at Natchez Women’s Center.  After 10 years of working there, she joined McComb OB-GYN Associates in 2017.

Kappi fell in love with Women’s Health while she was in graduate school and prayed that she would be able to find employment in that field.  She states, “I love the fact that I can relate to my patients due to my own past experiences.  I remember what it was like to be a teenager, a newlywed, pregnant, postpartum and am still juggling the demands of being a working mom. I also love learning from my patients that have had other experiences that I haven’t. To me, it is all about building relationships and providing compassion and encouragement to each other through every season of life!”

Kappi is married to Ron Rushing, who teaches and coaches football at Parklane Academy.  They have three kids, Tate , Kyle, and Karly. During her spare time, Kappi enjoys spending time with family and friends and cheering on her kids and husband in their games.  They are members of First Baptist Church of Summit.

After becoming a registered nurse, Diane worked for five years in various intensive care units at Ochsner Hospital in New Orleans, with the most time spent in Neuro ICU. She also worked for one year at Beacham Memorial Hospital in Magnolia.
