Dr. Natalie Marks Joins OpenVet as Chief Veterinary Officer

MIAMI, FL — February 12, 2026 — OpenVet, the creator of the first medical intelligence infrastructure built for the full complexity of animal health, today announced that Natalie Marks, DVM, CVJ, CCFP, Elite FFCP-V, has joined its core leadership team as Chief Veterinary Officer (CVO). Dr. Marks joins Founder and CEO Adam Sager and Co-Founder and COO Andrew Heller, DVM, to advance OpenVet’s mission to arm every veterinarian with the world’s best intelligence, empowering them to practice at the absolute limit of their professional judgment.

Dr. Marks brings over two decades of clinical leadership to OpenVet, having previously served as co-owner and medical director of Blum Animal Hospital, the largest small-animal practice in Chicago. A prominent voice in the profession, she is an Elite Fear Free and Cat Friendly Certified Professional and currently leads VANE, the most prestigious angel investor group in veterinary medicine.

“Natalie represents veterinary medicine at its best: rigorous, accountable, and grounded in real clinical responsibility,” said Adam Sager, Founder and CEO of OpenVet. “We’re building infrastructure veterinarians can rely on in the moments that matter. Natalie has observed that many veterinarians are challenged to make high-stakes decisions without complete access to information. That perspective will shape how we scale OpenVet in a way that strengthens clinical judgment and earns trust in practice.”

“OpenVet’s product-market fit is the most immediate I’ve encountered; it solves the fundamental pain of accessing expert-level intelligence at the point of care,” said Dr. Marks. “In light of the evolving FDA guidance for Clinical Decision Support (CDS) systems, it is clear the industry must move toward a standard of transparency and clinician-in-the-loop reasoning. OpenVet is the only platform already meeting this benchmark, providing a defensible clinical memory that empowers veterinarians to practice at their absolute peak.”

“In veterinary medicine, we don’t need tools that replace our judgment; we need systems that clarify our thinking under pressure,” noted Dr. Heller. “Natalie is a titan in this field. Her expertise ensures that, as we scale our computable medical framework, every insight remains grounded in the patient’s biological reality. She is the perfect bridge between the frontier of AI and the frontlines of the clinic.”

“I’m incredibly grateful for the opportunity to work with Adam and Andrew,” Dr. Marks said. “Their partnership exemplifies how great leadership drives meaningful innovation. Adam’s world-class technical rigor, shaped by safety-critical systems, paired with Andrew’s deeply respected clinical leadership, creates a foundation few startups ever achieve. Together, they are building OpenVet with the clarity, integrity, and vision needed to responsibly scale intelligence that truly serves our profession.”
