About Us

The Summit and Heritage Animal Clinics are full-service veterinary practices that together provide medical and dental care for pets at every stage of life in the Lake Country area and throughout southeastern Wisconsin.


Veterinary experts with a passion for pets

After years of veterinary training and experience Dr. Texeira is a specialist in wellness, diagnostic, dental and surgical care. Just as important, they are passionate about giving your special animal the care it needs to maintain good health and to address medical concerns, when necessary, so they can live happy and comfortable lives.


State-of-the-art veterinary equipment

Both clinics are state-of-the-art and fully equipped to offer onsite surgical suites and diagnostic imaging, so you don’t have to travel to another specialist or facility for treatment. We do most surgical procedures here, allowing your pet to be treated in a familiar place in which they already feel comfortable and by their doctor, who already knows them and their health history.


Caring for pet owners, too

Everyone at Summit and Heritage Animal Clinics goes beyond caring for pets… we care for pet owners, too, providing you with a valuable resource that you can count on when you have questions, concerns, or you just need advice. The doctors are pet owners, too, so they understand and relate to the joys and the worries that comes with being your pet’s caretaker.


We are happy to schedule house calls with established clients, and we’ll even make special arrangements to come to your home when your cherished pet is ready to say goodbye. We know that it’s a special honor to take care of your pet, and we are grateful for the opportunity.


Excellence in veterinary medicine since 1982

In 1982 there weren't any veterinary offices located in the Delafield area until Dr Sigmond took the leap to open the Heritage Animal Clinic. By 1988 he was able to join with the Summit Animal Clinic in Oconomowoc in order to satisfy his growing number of happy pets and owners. Dr.Texeira came aboard a few years later and upon Dr. Sigmonds retirement became the sole owner of Summit & Heritage Animal Clinics. Dr. Texeira partners himself along side highly qualified associates that offer our clients a diverse and top-notch approach to provide excellent care, advanced techniques that promise superior results, and genuine concern for pets and the families who love them. The doctors are always committed to staying on top of the latest developments in veterinary medicine through continuing education classes and conferences.
