About

My name is Kristy Stoffer, and my career has been built around understanding the human body—not in the abstract, but at the bedside, with the precision the operating room demands. As an active Certified Registered Nurse Anesthetist (CRNA), my clinical training is rooted in physiology, pharmacology, and the careful application of tools to support patients through physiologically demanding moments. Knowing how the body responds and adjusting in real time is the same clinical precision the Eingedi team brings to health optimization.

Outside the operating room, health and wellness have always been more than a profession to me. The daily practices that build resilience — movement, nutrition, sauna, cold exposure — are how David and I have built our life together.

It started in our own backyard. David began building saunas and cold plunges for people's homes, and we watched what these practices did for our family and friends. The more we saw, the more we wanted to share it — which is how Nightjar Sauna & Cold Plunge Club was born: soon to be West Michigan's first Finnish-style sauna club, built so our community could experience what we'd been living.

Peptide therapy was the natural next layer — a meeting point of my clinical background, years of studying peptides and metabolic health, and the wellness we already lived. What I kept seeing was people who were genuinely curious about peptides but had nowhere trustworthy to turn: conflicting information online, unclear sourcing, overseas suppliers, and no clinician to ask about dosing or what to expect.

That gap is what Eingedi exists to close. A prescription alone was never the point. What actually changes how you feel, perform, recover, and age is a coordinated strategy: trusted sourcing, objective lab data, appropriate peptide therapy, medical-grade supplementation, and the daily habits that hold it all together.

That's what Eingedi is — a clinician-guided health optimization membership for our community here in Grand Rapids and nationwide. The Eingedi care team handles onboarding, coordination, and day-to-day support, so clinical time is reserved for what matters most: clinical judgment. Routine questions get fast answers, and clinical concerns always reach a clinician.
