Jennifer Cooper is an Advanced Practice Registered Nurse and the Chief Nursing Officer of Dr. Well, the clinical umbrella under which Elixyr Labs operates. With extensive experience in primary care, longevity medicine, and procedural practice, Jennifer plays a pivotal behind-the-scenes role in the daily flow of patient care at Elixyr.

Andrea McAuliff is a critical-care nurse, certified personal trainer, and the creative force behind Elixyr Labs and Onawäna Athletics—two sister brands built on the belief that science and self-care should feel human, hopeful, and genuinely doable.
With more than two decades in nursing and a lifetime of curiosity about the human body, Dre blends clinical expertise with a coach’s heart and a creator’s imagination. Her work spans metabolic medicine, IV therapy, hormone optimization, fitness, nutrition, and longevity practices—delivered with a tone that’s equal parts science-literate and soul-forward.
She’s known for translating complex physiology into everyday language, designing wellness plans that actually fit real lives, and building spaces that feel more like retro summer camp than sterile clinic. In her world, data matters, laughter counts as medicine, and everyone deserves to feel strong, capable, and at home in their own body.
At Elixyr Labs, Dre leads patient care, protocol creation, IV therapy, metabolic support, and the hands-on clinical work that makes the practice feel deeply personal. At Onawäna Athletics, she brings fitness and nutrition to life through functional training, mobility work, seasonal menus, community events, and her signature “camp-style” motivation.
Clients describe her as the nurse who listens harder, the coach who actually shows up, and the rare clinician who can make evidence-based medicine feel like a conversation with a trusted friend. She is committed to helping people live longer not by luck, but by intention—one thoughtful practice, one informed decision, one moment of care at a time
Sarah McAuliff is a Medical Assistant, Certified Personal Trainer, and the heart-forward Head Coach behind Elixyr Labs and Onawäna Athletics. Before stepping into human health, she spent a decade as a veterinary medical technician—honing her clinical precision, calm under pressure, and instinctive ability to care for beings who can’t always articulate what they need. That blend of compassion, competence, and quiet steadiness now defines the way she supports our clients.
Sarah underwent a life-changing transformation of her own, losing 100 pounds of fat while gaining 8 pounds of muscle through the same protocols we use at Elixyr and Onawäna today. Her journey wasn’t quick or easy—which is exactly why she’s so effective as a coach. She knows what it’s like to feel overwhelmed, stuck, hopeful, determined, and finally proud. She brings that lived empathy to every client she works with.
As our Head Coach, Sarah guides training, nutrition support, and mindset coaching with a steady, encouraging presence. Clients trust her because she’s been exactly where they are—and she knows the science, the systems, and the emotional landscape of change from the inside out.
In addition to coaching, Sarah also runs key parts of Elixyr’s admin operations, keeping the engine running behind the scenes with organization, reliability, and her signature calm efficiency.
Her combination of clinical skill, personal transformation, and genuine care makes her an anchor in the Elixyr and Onawäna community—and a living example of what’s possible when science, structure, and self-belief line up.
