Who we are.

Aaryn Olesen is the co-founder of Myelina Health. Diagnosed with MS, Aaryn channels lived experience into building tools that meet women where they actually are: navigating symptoms, careers, relationships, and motherhood, often all at once.

Her path to this work spans more than two decades in pharmacovigilance, where she dedicated her career to patient safety — most of it at AstraZeneca — growing into leadership and executive roles along the way. Aaryn holds a Bachelor's in Psychology from UCLA, completed doctoral work at the University of North Carolina at Chapel Hill, and earned a Master of Public Health in Health Policy and Management from the Yale School of Public Health. She is a National Board Certified Health & Wellness Coach trained through the Mayo Clinic and a Diplomate of the American Board of Lifestyle Medicine.

Aaryn lives in Dana Point, California, where she draws daily energy from being near the ocean.

Brian Pentz is the co-founder and technical architect of Myelina Health. He is the founder of AI Keeps It Real, an applied AI practice that builds production multi-agent systems for individuals and small teams.

Brian is a Google for Startups alumnus, selected as a founder in the program, and a licensed professional with experience across real estate and finance — backgrounds that taught him how to operate in regulated environments where details matter and trust is earned slowly. At Myelina Health, he is responsible for the privacy-first infrastructure, the multi-model AI stack, and the data pipeline connecting Apple Health, Oura Ring, and patient-reported outcomes.

Brian lives in California with his wife and their child.
