Meet Peter Kozlowski, MD
Dr. Peter Kozlowski is a functional medicine physician who has been practicing root-cause medicine since 2011, with a foundation in Family Practice and a longstanding commitment to helping patients make sense of complex chronic symptoms. He is known for translating complicated health topics into clear, practical next steps while keeping a thoughtful, evidence-informed, whole-person approach at the center of care.
His clinical interests include gut health, the microbiome, SIBO, food sensitivities, immune balance, hormones, detoxification, genomics, cardiovascular health, infertility, addiction and recovery, and the mind-body connection. Whether working with patients or teaching clinicians, Dr. Kozlowski’s focus is the same: uncover the deeper patterns driving illness and help people move from confusion toward clarity and healing.
Since September 2025, Dr. Kozlowski has served full-time as Director of Clinical Intelligence at Ortho Molecular Products. He is also the creator of Root Cause Practice Pro (RCPP), an AI-powered platform designed to support clinicians and individuals navigating chronic health concerns with structured, evidence-based protocols across complex conditions, and he serves as Chief Medical Officer of HANS, an AI platform built specifically for functional medicine workflows.
Dr. Kozlowski is the author of Unfunc Your Gut and Get the Func Out, and he is a nationally recognized speaker who has presented for organizations including IFM, A4M, and PLMI, as well as for laboratories such as IntellxxDNA and Mosaic Diagnostics. He has also worked as a clinical writer for Function Health, contributing educational content in support of its comprehensive lab testing platform and patient-facing health initiatives.
At the heart of his work is a simple belief: patients deserve to be heard, understood, and guided with both wisdom and clarity. His approach combines careful listening, root-cause investigation, advanced clinical insight, and practical strategies that help patients take meaningful steps toward lasting health.

Meet Brian Grimaud, DO
Dr. Brian Grimaud brings over 15 years of critical care experience and a deep commitment to root-cause medicine to his work with patients. A board-certified anesthesiologist, Dr. Grimaud spent more than a decade caring for patients in the operating room and critical care settings — an experience that sharpened both his clinical judgment and his conviction that conventional medicine too often treats downstream symptoms while the true drivers of illness go unaddressed.
While his love of medicine and physiology first led him into anesthesiology, Dr. Grimaud has long been drawn to the natural, biochemical, and lifestyle-based foundations of health. Witnessing firsthand how unaddressed root causes lead patients down a path of escalating medications and avoidable surgeries deepened his resolve to practice differently. He is currently completing his certification through the Institute for Functional Medicine and has devoted countless hours to independent study under leaders in the field.
Dr. Grimaud believes that lifestyle, nutrition, environmental exposures, and genetics are among the most powerful — and most overlooked — determinants of long-term health. His approach centers on understanding each patient's biochemistry at the cellular level, identifying what is driving dysfunction, and giving the body what it needs to heal. He is honored to partner with Dr. Kozlowski in expanding access to this kind of care.
