Our Story

At its core, VSx Chicago is a practice built for the community we belong to—the community of veterinarians who trust and collaborate with us to deliver the specialized care their patients need. 

We also uniquely understand the challenges that GP veterinarians face: 

  • Our CEO Chase Michalek is the former owner of 16 GP veterinary hospitals 

  • Our co-founder Dr. Frederickson, is a general practice DVM with over 15 years of experience as a referring DVM to surgery departments across the Midwest– first as an associate GP veterinarian, then as an emergency veterinarian and finally as the owner of several general practices. 

  • Our founding surgeon, Dr. Wosar, has worked shoulder to shoulder with referring GP veterinarians and owners for the past 6 years in their very own operating rooms as the owner of a well-respected mobile surgery practice. 

This "community" approach with our veterinarian referral partners is a crucial differentiator for VSx.

Additionally, our practice focuses exclusively on surgery, allowing veterinarians to trust us with their most complex cases while knowing there will be no multi-specialty distractions. We offer tailored support and care coordination that ensures the best outcomes for both patients and pet owners.

As a bootstrapped and entrepreneurial team with no corporate funding, we’re committed to being at the forefront of high-quality, innovative veterinary surgical care—always with an eye toward how we can better serve our referral community. Together, we’re creating a new future for veterinary surgery in Chicago, one that’s built on trust, an exclusive focus on surgery, and a deep commitment to the community we serve.
