I design health and creative products people aren’t ashamed to live with.

Most products in healthcare fail at the human layer, not the mechanical one: motivation, anxiety, dignity, routine. My work starts with primary research, finds the insight everyone else stepped over, and turns it into design decisions I can defend line by line. Every case study below pairs each major decision with its  because.

Reblossom

Fine motor rehabilitation, reframed as Ikebana.

The Problem

Stroke survivors need thousands of fine motor repetitions to rewire hand function, and most of that work happens at home, unsupervised. Home programs collapse there: the standard tools are beige clinical pegboards that read as homework about disability.

The real users are overwhelmed patients and stretched-thin caregivers. Existing products serve neither.

The Insight

Rehab tools don’t fail mechanically. They fail motivationally. Ikebana flower arranging already is graded fine motor therapy: reach, pinch, rotate, place, steady.

If every repetition produced something beautiful enough to keep, adherence would stop being the patient’s burden and become the product’s job.

Iteration

A clay and resin concept won a Special Prize at WIRED’s Creative Hack Awards. Successive prototype generations were shaped by occupational-therapist feedback, and the current design is re-engineered for manufacturability: rubber overmolding, injection-molded sliders, magnet and weighted-fabric assembly.

Design Decisions, and Why

Stems are flexible, rubber-overmolded wire
BecauseBending and guiding each stem is the resistance work. The material behavior is the therapeutic mechanism, not a compromise.
Flower tops attach magnetically
BecauseIt adds a pinch, align, and place task, and every rep ends in a felt click of success. Feedback without screens.
Weights are concealed inside the fabric flower tops
BecauseGraded loading shouldn’t look like a dumbbell. Difficulty hides inside beauty, so progression never looks clinical.
Difficulty lives in interchangeable modular sliders, on two axes
BecauseVarying aperture size and approach angle lets one object span early gross grasp to late fine dexterity, and lets clinicians prescribe precisely.
The finished arrangement is meant to be displayed
BecauseProgress becomes décor. Nothing to hide in a drawer when guests arrive. The product respects the user’s home and dignity.

The Problem

LGBTQ+ Americans report some of the highest rates of unmet healthcare need. We didn’t start with a product. We started with why.

The Research

Months of primary research through a trauma-informed lens: LGBTQ+ patients (emerging adults, 18–35), cardiologists, primary care physicians, and health-system leaders across Penn Medicine’s LGBTQ Health program, trans resource centers, and community organizations.

“I would do it for the sake of living, but I would not do it if I didn’t need it.”Patient, on preventative screening
“At home, numbers will almost always be more accurate.”Primary care physician

Iteration

We first iterated a full “healthcare at home” kit, a box system for routine self screening, then narrowed to the single highest-leverage touchpoint. One object done right beats a box of average ones.

The Insight Chain

  • Fear of discrimination keeps people out of the clinic. Patients described downplaying symptoms and skipping anything that wasn’t urgent. “If I’m not dying, I’m fine.”
  • Avoidance compounds hardest in cardiovascular health. Hypertension is the silent killer: it only surfaces through the routine measurement these patients avoid.
  • Home should be the answer, but home monitoring fails in practice. Cuffs are fumbly one handed, anxiety inflates the first reading, devices vanish into drawers, logging lapses. Even physicians told us they don’t keep up with it.
  • So the intervention point isn’t the clinic or an app. It’s the cuff itself.

Design Decisions, and Why

BOA dial closure, no Velcro
BecauseOne-handed, repeatable fit at consistent tension: easier for every body, and consistent tightness makes readings comparable day to day.
Designed to live on the table
BecauseAn object you’re proud to display is its own reminder. Visibility is the compliance mechanism.
Reminders and logging built into the ritual
BecauseClinicians act on trends, not single numbers, so the product carries the record keeping burden patients reliably drop.
The ritual is calm by design
BecauseThe first reading is always the highest. Pacing the experience around settling down produces more truthful numbers.

Hermit

A curated marketplace for artists, with artists.

The Hermit landing page on a tablet: a curated platform for custom fine art, made by artists for artists
Answer questions, get matched, receive your commission

The Problem

In 2016 there was no established market where an artist could earn commissions and breathe. Representation ran through galleries, which took 50 to 70% of every sale and held the leverage that came with it.

The alternative, open marketplaces like Etsy, priced work like a craft fair, and being there could cost a serious artist their reputation.

The Insight

The gap was never price. It was power and positioning. Artists didn’t need a cheaper storefront; they needed a venue with gallery credibility and none of the gallery extraction.

Buyers wanted unique commissioned work and had no reliable way to find the right artist.

What I Carried Forward

Hermit was for artists, with artists: a platform built inside a community I belong to, made to bring power back to the creator.

Illness forced a pause, then a pivot. I take real pride in what we built, and I plan to return to it one day.

The discipline carried straight into Reblossom: curated trust, dignity for the end user, and power kept with the people the product serves.

Design Decisions, and Why

Every artist was hand-curated
BecauseCuration was the product: gallery trust for buyers, protected reputations for artists. Being on Hermit was a credential, not a liability.
Matching came before browsing
BecauseA commission starts as a fit problem, not a search problem. Buyers described the work they wanted; Hermit matched them to artists who made that kind of work.
Positioned deliberately between Etsy and the gallery
BecauseThe middle was empty. Hermit priced above craft fair signals and kept its cut far below the gallery standard. Price integrity for the artist, fair access for the buyer.
Grown from matching into a two-sided marketplace
BecauseOnce fit and trust worked, supply and demand could compound: buyers who wanted unique work, artists who wanted to make it.

How I Work

The same discipline, every time.

1

Research First

Primary research before pixels or plastic. Patients, clinicians, experts, and systems, seen through the lens of the people the product has to serve.

2

Find the Insight

The finding everyone else stepped over: rehab tools fail on motivation; the cuff, not the clinic, is the intervention point.

3

Decide, with Reasons

Every major decision paired with its  because. If I can’t defend a choice from the research, it doesn’t ship.

4

Ship Evidence

Clinical use, examiner findings, awards. Validation from the world, not the pitch deck.

About

I’m a product designer and founder working at the intersection of healthcare, craft, and daily life. I trained in art at the School of the Art Institute of Chicago and in engineering, design, and business at the University of Pennsylvania (MS, Integrated Product Design). My sensibility comes from Japanese craft tradition: material first making, restraint, and objects built to be lived with.

Before founding companies I was a digital artist with international design awards and over a million digital products sold. That background shows up everywhere in my work: I believe beauty is a feature with clinical outcomes.
