Meet Dr. Mark Beerenstrauch, the driving force behind Pet Health and Pet Care, where the mission extends beyond exceptional veterinary care. His vision is to revolutionize the veterinary experience for pets and their parents, ensuring that visits are more personalized, enjoyable, and fulfilling—not just for pet families but the entire team.
What sparked his journey into veterinary medicine? An unexpected companion, Nita. This dog changed the course of his life, shifting his focus from business management to pet care. Over two decades later, he has cultivated this passion into a career that redefines what veterinary medicine can be.
Unsatisfied with the impersonal nature of high-volume and corporate veterinary settings, he founded Pet Health in Las Vegas, where quality care, personalized experiences, and scientifically backed treatments are at the heart of every decision. Now, with the opening of Pet Care in Henderson, this vision is expanding—bringing the same dedication to excellence, extended appointment times, and integrative care to a new community.
At the core of his approach is a deep commitment to transforming the pet parent experience and elevating his team’s expertise through rigorous training. Every interaction is designed to be meaningful, every visit comforting, and every team member empowered to provide the best care possible. Inspired by the latest innovations in both veterinary and business practices, Dr. B continues to cultivate a culture of empathy, excellence, and continuous learning.
Outside of Pet Health and Pet Care, Dr. B enjoys time with his family, the companionship of their beloved pets, and a deep connection to the land through their family farm in Nebraska. Photography and his love for sports—especially all things University of Nebraska—provide a perfect balance to his passion for veterinary medicine.
Jaclin Shaddox has been a valued member of the Pet Health team since 2021, bringing her dedication to compassionate care and professional service to every interaction. Her journey in veterinary medicine began as a young mother looking for a meaningful career. She discovered her passion for helping pets and their families while working at a veterinary clinic. That rewarding experience sparked a lasting commitment to the field and eventually led her to Pet Health.

Jaclin finds the greatest fulfillment in positively impacting the lives of pets and pet parents, ensuring they feel heard, valued, and informed. She builds strong connections with pet parents through empathetic communication and excellent customer service. Her collaborative approach with the Pet Health team ensures that each patient receives the highest level of care in a supportive and welcoming environment.

At home, Jaclin is a proud pet parent to two energetic Labrador Retrievers, who fill her life with joy and unconditional love. Her experiences with her pets deepen her understanding of the bond between animals and their families, which she channels into her work at Pet Health.

Outside of work, Jaclin enjoys spending time with her two sons, whether on adventures or enjoying quiet moments at home.
