Former Modernizing Medicine sales leader joins Bonsai to accelerate growth of its agentic AI platform for healthcare practices.

Bonsai Health, the agentic AI platform automating complex healthcare workflows, today announced that Rick Trefzger has joined the company as Chief Revenue Officer (CRO).

Trefzger joins Bonsai after nearly 11 years at Modernizing Medicine (ModMed), where he was an early employee and served as vice president of sales, helping scale the company into the leading specialty-specific EHR platform serving dermatology, ophthalmology, orthopedics, gastroenterology, and other core specialties. During his tenure, ModMed grew into one of the most widely adopted specialty technology platforms in the U.S., transforming how medical practices operate and deliver care. He most recently served as vice president of global software sales at IDEXX (Nasdaq: IDXX).

The appointment follows Bonsai’s recent $7 million seed raise, led by Bonfire Ventures and Wonder Ventures, as the company expands its agentic AI platform to help practices improve patient outcomes, reduce administrative burden, and drive sustainable growth.

“Rick’s experience at Modernizing Medicine gives him an unmatched understanding of specialty practice workflows and the challenges providers face at scale,” said Travis Schneider, co-founder and co-CEO of Bonsai Health. “He’s proven he can build and lead high-performing teams that drive real transformation. Rick shares our belief that AI can reshape how practices operate, improving access, reducing burnout, and ensuring every patient gets the care they need.”

At Bonsai, Trefzger will oversee all go-to-market functions, including sales, marketing, and business development, with a focus on expanding the company’s presence and deepening partnerships across medical specialties.

“Bonsai is defining an entirely new category of practice automation, AI that actually does the work,” said Rick Trefzger, chief revenue officer of Bonsai Health. “The platform’s early traction shows just how transformative this model can be for practices and patients alike. I’m thrilled to join this exceptional team and help scale that impact.”

“Rick is a proven leader with a rare combination of strategic insight and operational rigor,” added Luke Kervin, co-founder and co-CEO of Bonsai Health. “As we continue to grow, his leadership will be instrumental in bringing Bonsai’s AI to more practices.”
