Andrea Hemmen DVM is a native of Wichita, having earned her Bachelors of Science at Wichita State University in 2005 and her veterinary degree from Kansas State University in 2009. Dr. Hemmen began working at Oakcrest Pet Hospital in 2003 as a kennel attendant and discovered her love for veterinary medicine there.  Over time, she took on reception and technician duties and eventually pursued her veterinary degree.

Upon graduation from veterinary school, she started practicing as a small animal veterinarian for a clinic in Augusta, KS.  After 2 years, she returned home and joined the doctors at Oakcrest Pet Hospital.

Dr. Hemmen enjoys many areas of veterinary medicine especially ophthalmology and internal medicine. She is a member of the Wichita Veterinary Medical Association, Kansas Veterinary Medical Association and the American Veterinary Medical Association. In her free time, she likes to spend time with her family and friends. She is active in her church and enjoys traveling, camping and hiking. She also enjoys spending time with her dogs, Fortune and Cinder, her cats, Willow and Boo, and her three chinchillas, Louise, Clover, and Poppy.

Edgar Ocampo DVM is also a Wichita native.  He attended East High School and graduated from Wichita State University with a Bachelors of Arts in 2012.  After earning his veterinary degree in 2016 from Kansas State University, he joined the team at Oakcrest Pet Hospital.  Dr. Ocampo brings an array of knowledge and skills to the practice, including being fluent in Spanish.

Dr. Ocampo has a special interest in exotic animal medicine, particularly wildlife conservation.  While attending KSU, he was able to take part in a research study involving flamingos and had a chance to assist in surgery on a blue iguana.  In addition to exotic animal medicine, Dr. Ocampo also enjoys the areas of cardiology and internal medicine.

When he is not working with animals, Dr. Ocampo enjoys hiking with his beautiful wife, Robin, or spending time with their dogs, Charlie, Pickles, and Olive. Dr. Ocampo and Robin also have two cats at home, Max and Piper.  In the future, he wants to travel more and expand his 'furry family'.

Sarah Dugan DVM grew up in Emporia, Kansas on a farm with 20 acres of land and a variety of animals.  Her participation in 4-H as a child gave her experience with dogs, horses, and sheep.  She especially enjoyed training and showing horses and dogs.  One fond memory includes her favorite mare, Good Golly Miss Molly, whom she showed in a trail class. 'She tried to spell out her name with the logs!'

While in high school, Dr. Dugan worked part time at her father's mixed animal practice in Emporia. 'When I got promoted to working as a receptionist, I realized I really enjoyed working with clients and their pets, and I decided I wanted to be a veterinarian.'  Dr. Dugan's decision made her a third generation veterinarian as she comes from a long line of veterinarians including her grandfather, grandfather's brother, father, father's brother, older brother, and sister-in-law. 

Dr. Dugan received her DVM from Kansas State University College of Veterinary Medicine in 2003 and completed a year-long Large Animal Medicine and Surgery internship at Texas A&M  University. She then spent two years practicing medicine in Thomasville, GA before moving to Wichita.  She has been practicing in the Wichita area for 16 years and joined Oakcrest Pet Hospital in 2022.

Dr. Dugan and her husband, Ryan, a Wichita native, have two children, Max, 16 and Liza, 14. 'We are busy with family,' she says, 'following sports, school activities, and family events in Wichita and Emporia.' Their family also includes two dogs: Enzo, a Chihuahua/Italian greyhound mix ('who can jump waist high') and Portsy, a Jack Russell terrier ('cute, loving, but not the sharpest knife in the drawer').

Past president of the Wichita Veterinary Association
