By 1986, after four successful years at the Humane Society facility, Dr. Sullivan decided it was time to find a permanent location for her clinic. She purchased a property at the corner of Greenwich and E. 31st Street S, which included a large metal building and a house. Transforming the space into a clinic came with its challenges—she navigated restrictive land covenants, appeased neighbors, and worked with the metropolitan planning board. With a new baby, a growing practice, and her own horses, it was a lot to manage. Blair drafted the initial plans to remodel the metal building into a small animal and equine veterinary clinic, which draftsmen turned into official blueprints. Blair’s father supervised the remodeling project, handling painting, material runs, and more. Dr. Sullivan used an inheritance from her father to purchase essential equipment, and during construction, she saw patients in the property’s house. The remodel was completed in December 1986.

In 1994, Dr. Sullivan expanded the clinic by doubling its size with a new addition. She credits Valley State Bank in Belle Plaine for granting her a small business loan when larger banks were hesitant because the clinic and home shared the same property. Over the years, Dr. Sullivan continually upgraded the facility, adding modern finishes and technologies, including one of the first ultrasound machines in the Wichita area. Dr. Sullivan’s commitment to excellent veterinary medicine and compassionate care meant she never needed to advertise. Word-of-mouth referrals from satisfied clients kept her schedule full. She remained a solo practitioner until 1992, when she hired Dr. Cheryl Schmidt. By 2008, the clinic grew into a three-veterinarian practice, allowing for shared on-call duties, which was a welcome change after years of being on-call every day.
