Dr. David James


Dr. David JamesDr James was born and lived in South Africa until the age of 24. He grew up in a mixed animal veterinary practice and his father is still a practicing veterinarian in South Africa today. Much of his childhood was spent on the farms near his home town where his father traveled to treat sick animals. It was during these formative years that he developed a love of the outdoors and for animals both domestic and wild. He has a passion for African wildlife and has been able to share this world with his wife and two daughters during their annual trips to catch up with their family and the African bushveld. Encounters with lion, elephant, hyena, zebra and giraffe are always possible.

Dr James completed his Bachelor of Veterinary Science at the University of Onderstepoort in Pretoria, South Africa in 1992. He then moved to the UK where his first job was in Scotland caring for cattle, sheep, horses, dogs and cats. His love of small animals then caused him to move to London and concentrate only on dogs and cats. During this time he met his future wife, who is American by birth, and they traveled extensively in Europe.

They moved to Charlotte in 1998; found North Mecklenburg Animal Hospital and it has been a very exciting place to grow as veterinarian.

Dr James and his family live in Huntersville and share their home with a dog Tally and two black and white cats, Mafuta and Zoza ( Zulu names meaning “Fat Boy” and “ She struts about”). In his spare time he likes to fly fish, cycle, kayak and go hiking and camping with his family.

Dr James enjoys challenging medical cases as well as general surgery (soft tissue, oral and orthopedic).

He is a certified PennHIP veterinarian and is passionate about improving our dogs hips through proper screening techniques.

Along with other doctors in the practice he is committed to using advanced imaging and minimally invasive surgeries to improve patient comfort. Ultrasonography, laparoscopy, arthroscopy and cystoscopy are examples of minimally invasive techniques which are employed at our hospital.

Dr. Paul KritzingerDr. Paul Kritzinger was born in Namibia in southern Africa and spent his youth growing up in the African wilderness. A family of outdoor and wildlife enthusiasts, they spend every opportunity they had exploring the continent and visiting game reserves and wildlife refuges. This resulted in an initial desire to follow a career in wildlife veterinary services which was shortly curtailed up too many close encounters with wild animals. He was once seen sprinting across the veld wearing only his shoes, with an enraged bull elephant hot on his heels.

He attended high school at the prestigious Diocesan College in Cape Town South Africa. Afterwards Dr. Kritzinger attended the University of Pretoria in South Africa where he received his veterinary degree in 1993. On completion of his studies he traveled to England and began practicing in the quaint town of Ashford in the English countryside. Dr. Kritzinger spent six years in England honing his surgical & medical skills. While living in London he was privileged at times to treat some of the Queen’s horses and the musician Sting’s dogs. He has traveled extensively in Europe as well as the Himalayas, and on returning from one of these adventures, he met Sandy whom he later married in South Africa. After meeting Dr. Schaaf through his longtime friend Dr. James, they immigrated to North Carolina in 1999 and Dr. Kritzinger began working at NMAH. Dr. Kritzinger and Sandy now live in Cornelius on Lake Norman with their son Felix and daughter Jordan. Their rescued pets are a golden retriever Maya and Ribeye the cat. Their passion for outdoor activities takes up their recreational time and they can often be found camping in the North Carolina Mountains, in the rain, or fly fishing in various parts of the country. Former competitive triathletes they also enjoy a lot of trail running, road cycling and mountain biking.

Dr. Lisa Wyant

Associate Doctor

Dr. Wyant is a native of eastern Pennsylvania and raised in a family who were avid show dog enthusiasts. She picked up her first competitive leash with her family’s first Alaskan Malamutes when she was 9 years old and discovered a passion for animals.  She has raised and shown pure bred Shiba inus and been an active member of that community for over 30 years.

Dr. Wyant loves everything pertaining to medicine and the human and animal body. This is what drove her to join the research community and complete a masters program in human physiology at Temple University, where she successfully published many peer reviewed papers in cardiology.  Her experience in research only fueled her drive to become a veterinarian and so she went on to complete her VMD at the University of Pennsylvania Veterinary School in 2002.

Dr. Wyant is also an avid outdoor enthusiast and it is this love of nature that took her to the mountains of Utah for the last 15 years, where she has added an incredible amount of experience in surgery, internal medicine and critical care medicine while working for a referral center and owning her own practice.  What she also discovered in her experiences was that her deepest desire, other than taking care of animals, is the connections and bonds that can be formed with the people that are owned by these big and little critters.  Her goal is to attempt to make your experience when visiting the veterinary office pleasant, calming and confidence building no matter what the circumstance of your visit may be.

Dr. Wyant met her soul mate Jeff on the ski slopes of Park City, Utah. They have had many adventures traveling the world together and in 2016 her whole family of 2 Shiba Inus (Stewie and Britney) and Labradoodle Loki moved to the great state of North Carolina to be closer to family after the exciting birth of their daughter Charlotte Sophia Wyant.

When she has a free moment, you can usually find Dr Wyant and her clan searching for an adventure in a foreign country or in NC they are in the mountains, in the water, running, on the trails hiking and yes, still trying to find the powder on the ski slopes of NC and the Rockies.

Dr. Wyant looks forward to meeting and serving the community of Lake Norman and beyond with their pets needs.
