Rainier Partners, a private equity firm, completed the acquisition of Pet Food Express, an independent pet retailer, dedicated to helping pets live longer, healthier lives. Financial terms were not disclosed. “For over 30 years, my business partner Mark Witriol and I grew Pet Food Express without outside investment, so when it came time to choose a partner, we were very selective. We wanted a partner that truly understood our mission and our work in the pet community. We were extremely fortunate to find a cultural match with the team at Rainier; we could not be more excited for what the company will accomplish with Rainier’s support,” Michael Levy, PFE Founder and CEO.
