I Design Clinical Products Patients Actually Use.

Associate Director, Product & Experience at EO Care. I build the prototype in working code, test it with clinicians and patients, and ship what holds up.

Open to lead and senior product design roles. Raleigh, NC and remote.

Beyond the prototype

A patent-pending prediction system. A care plan reaching hundreds of patients. Referrals from eight cancer centers. Selected for Mayo Clinic Platform Accelerate. Platform data in research presented at ASCO.

The work spans product design, clinical implementation and real-world research. EO Care joined the October 2026 cohort of Mayo Clinic Platform Accelerate. EO’s clinical team presented an ASCO 2026 abstract on data from the care plan and check-ins I designed.

Clinician-Guided Symptom Care, Reaching Hundreds of Patients

Patient experience · Clinical product design

EO Care is the live care plan for pain, sleep, anxiety and nausea, free to anyone who needs it and the platform Mayo Clinic, MSK, Penn and five other cancer centers refer patients into. Three decisions shaped it: the plan carries its reasoning, feedback is a loop, and progress is something the patient can see.

Sarah's Care Plan: an action item to complete her check-in, a note from her care team, and a link to see how her goals are trending Product card: Daily Balance Tincture, subscribed, two a month, with Manage Subscription Her subscription: next billing date and each product she is subscribed to Message center: she writes that late afternoons are still tough, the care team raises a dose, and Your care plan was updated Progress: your first three months, Sarah, with her walking goal getting easier against a target Progress: sleep improving across her check-ins against the line patients like her typically reach, with a You Are Here marker
The patient's loop, left to right: her plan, a product, her subscription, a message that changed the plan, then her progress. From the app's front-end build.Swipe for more, tap any screen to zoom

Predicting Cancer Treatment Symptoms Before They Hit

Predictive healthcare · Clinical workflows · Patent pending

EO Care 360° is clinical decision support for the side effects of cancer treatment: Bayesian models forecast a patient's next 30 days, the oncologist approves one plan, and the patient app carries it. Selected for Mayo Clinic Platform Accelerate, October 2026.

Patient app, Today's Plan: how she feels, then the day's plan The check-in answered and opened for a few words Patient app, Journey: scores against the predicted curve Patient app, Shop: what the plan needs, with a nudge before it runs out Predictions: likely symptoms over the next 30 days as bars Model detail: a card per symptom with probability, severity and drivers Plan tab: Your Calls cards and the scored treatment plan Review and Sign: every order signed, one at a time or all at once
The patient app first: her day’s plan, the check-in, her scores against the predicted curve, and what the plan needs. Then the clinician’s four screens, from forecast to sign-off.Swipe for more, tap any screen to zoom

About

I see what others overlook, uncover what’s not working, and make complex things intuitive.

That started as journalism: at UNC I reported for Our Chatham, a local news project for a county that had little, and started its Spanish-language edition. Since then, six years in health and consumer products, a Techstars company, and almost four years leading design at EO Care, always in one loop: a prototype in code before a deck, working HTML handed to engineering, one metric per change read in the analytics.
