Doctor Creighton, founder of NVA



In 1996, after 23 years as a practicing veterinarian, I realized the business of animal care was changing. There were fewer veterinarians coming out of school ready to buy a practice from a retiring veterinarian. Between student debt and the increasing complexity of running a business, I could not blame them.

To preserve local veterinary practice, I started to buy veterinary hospitals from other veterinarians who were retiring. Taking over another veterinarian’s practice is a big deal and a responsibility we did not take lightly. My team and I believed that veterinary medicine is best practiced when a local veterinarian crafts their own approach to patient care.

When a hospital joined NVA, we preserved their identity by maintaining the hospital’s culture, people and name. We provided support for the more onerous parts of business, hiring experts in accounting, recruiting, legal, marketing and operations to share across all our hospitals. Through it all, I aimed to foster a doctor-friendly environment where doctor and staff satisfaction was high, new veterinarians could focus on what they love and people were proud to be a part of the NVA community.



When Stan entrusted me to be CEO of NVA, I was humbled and excited. Taking over a friend's business is a big deal and a responsibility I did not take lightly. Every day I work to honor what Stan built and deliver on his vision. To this day, that commitment continues of creating a culture of servant leadership and support.

We continue to partner with general veterinary practices and have expanded into specialty and ER hospitals and pet resorts. Our community includes animal care services in the United States, Canada, Australia and New Zealand. We hire experts and deliver greater, more advanced tools to keep our community thriving, while encouraging each doctor or animal care expert to run their business as they see fit.

Since Stan founded NVA over 20 years ago, many have entered veterinary hospital ownership because it's a great business. We are still in it because we believe it's a profession that does great things.
