Tyree & D’Angelo Partners (TDP), a Chicago-based private equity firm with a thesis-driven, buy-and-build strategy, announced the closing of a single-asset secondary transaction to extend its investment in Western Veterinary Partners, a fast-growing, veterinarian-centric general veterinary support company based in the United States.
The transaction establishes a continuation fund managed by TDP and raises new capital to support Western’s strong organic growth and upcoming acquisitions. The fund was anchored by HarbourVest Partners as the sole lead investor, with additional commitments from Ares Private Equity Secondaries funds, a syndicate of investors, and TDP’s existing limited and general partners.
Headquartered in Denver, Colorado, Western Veterinary Partners offers comprehensive veterinary services nationwide and has established a strong national presence. The company’s mission is centered on improving the lives of veterinarians and enhancing care for companion animals and their pet parents. Through continued clinical training, mentorship, and access to advanced hospital technology, Western’s affiliated veterinarians benefit from aligned equity ownership and professional support.
Western has maintained a leading position in veterinarian hiring and retention, which has been key to its market-leading organic growth. Its strategy of focusing on clinical excellence and professional well-being has positioned it as a partner of choice for veterinary business owners and clinicians across the country.
The continuation fund allows TDP to deepen its long-term partnership with Western, further strengthening its position as one of the fastest-growing and top-performing general veterinary services companies in the United States.
Support: William Blair served as exclusive financial advisor to Western and TDP, while Kirkland & Ellis represented TDP as legal advisor. Winston & Strawn acted as legal counsel to Western, and Ropes & Gray served as legal advisor to HarbourVest Partners.
