Our Story
Meet the founder
Dr. BreAnne Feldman Losik
Dr. BreAnne Feldman Losik grew up surrounded by veterinary medicine and business ownership. Both her father and grandfather are/were veterinary practitioners, entrepreneurs, and successful business owners. This exposure to veterinary medicine and the varied business opportunities within the profession helped to shape her education and career. Dr. Feldman received her Doctor of Veterinary Medicine from Iowa State University in 2008. She went on to complete a small animal rotating internship followed by several years in ER/specialty medicine before transitioning to private practice ownership and partnership of four hospitals across the Chicagoland area. Partnership and management in these hospitals further fueled her drive for entrepreneurship and business growth.
In 2017 she co-founded 4 Paws Imaging, a mobile company for ultrasound and echocardiogram which provided the ability for diagnostics to stay with the primary practitioner. In the last five years 4 Paws Imaging has grown to service over 165 hospitals in Chicagoland with 8 trained/certified sonographers, and is still actively growing. In 2021 she and her partners launched Elite Veterinary Teleradiology, a remote teleradiology company dedicated to imaging interpretation.
After 10 plus years in partnership, Dr. Feldman is shifting her focus to founding Radiant Veterinary in Naperville. It is very important to Dr. Feldman to maintain empathetic, quality medicine and (she) is excited to bring privately owned compassionate care with cutting edge diagnostics to the pets and families of north Naperville.
In addition to Dr. Feldman’s varied business pursuits, she sits on the board of Tiny and Tall Chicagoland rescue. She strives to be an example for women in business, leadership, and veterinary medicine, showing by example that it is achievable, feasible, fulfilling, and rewarding.
Along with her husband, Rob (a native of Naperville), they have two children and two dogs. Being a veterinary entrepreneur and mother keeps her very busy but she still tries to find time for reading a good book, gardening, or going for a run.

Our clinical decisions are evidence- based, detail-oriented, and guided by the latest in veterinary science. Every member of our team is relentlessly dedicated to professional growth and clinical precision, delivering care that’s not only thorough and cutting edge, but always tailored to the unique needs of each patient.
Integrity: Trust is the cornerstone of everything we do. At Radiant Veterinary, integrity means complete transparency, honest communication, and doing what’s right, even when no one is watching.

THE TEAM
Karen Kunst - Operations Manager
Karen has been in the Veterinary field since 2009, having attended the Veterinary Technician program at Winsted Community College in Winsted Connecticut. She started her journey at Bolton Veterinary Hospital, as an Outpatient Technician. After moving to Illinois in 2015, she continued her journey as an Emergency Technician at CARE Animal Emergency Service.
In 2018, Karen joined the management team there as an Assistant Manager, before transferring to Hospital Manager at Foxmoor Veterinary Clinic in 2020. Foxmoor was a part of National Veterinary Associates, therefore, she was able to work for corporate veterinary medicine before deciding private practice would allow her to focus more on personal patient care vs. corporate finances.
Joining Radiant Veterinary in 2026, brings her new exciting opportunities for her personal journey in this field as well as meeting new clients and patients. You might find one (or several of her eight dogs) running around the hospital, so make sure you say hello!
