About Us

About Us

At Pieces, we are passionate about leveraging technology that helps people help people advance their health and wellbeing.



Our journey started at Parkland Health & Hospital System, Dallas’ large safety-net hospital system, when our founder, Ruben Amarasingham, MD, began developing predictive models to reduce hospital readmission rates.

His work resulted in the creation of the non-profit research institute, PCCI, which has received more than $50 million in scientific funding. Pieces grew out of PCCI as a nimble hub of innovation and problem-solving for organizations around the globe.


Our Mission is to better people’s health.






Our guiding principles

Healthcare delivery and social services are fundamentally sacred missions. We revere our customers for the work they do.
We value positivity. We work on some hard problems, sometimes under tight
deadlines, but this is all made better if we foster, recruit, and build positive, enthusiastic,
humane, problem-solving individuals that love to be here.
We will always do and be better when we harness the collective strength,
unity, and intelligence of our team rather than relying on the brilliance of any one individual. We
value mutually supportive, high-trust, high-functioning teams and relationships.
We will hold each other to unquestionable standards of honesty and ethics in words and actions and operate with transparency.
We will hold ourselves, individually and collectively, accountable for adherence to our values and all other commitments we make.

Company Diversity

We believe strongly in the power of great ideas to address a variety of problems
across a wide spectrum of people. We want our staff to reflect that diversity of thought, experience and


Better ideas
The best ideas come from the intersection of different cultural, experiential, and social perspectives.
Wider and inclusive perspectives
We are all enriched through the sharing of differing viewpoints.
Varied experiences
