“Our promise is to assure that the assets and investments (people and places) of an organization are performing at their optimum.”


Enviah puts health and care back into healthcare environments.

Enviah is taking the lead in developing ways to align built environments with operations, by removing the barriers that are working against staff success and patient satisfaction. Rather than designing spaces around the existing processes and culture, Enviah designs processes, cultures, and spaces oriented around our clients’ goals.

Enviah works at the intersection of medicine and processes, people and systems, spaces and technology, bringing an evidence-based strategy to people-centered projects. Using thoughtful research, targeted studies, and statistical analysis, Enviah provides critical and reliable data about systems integration to decision makers, increasing the likelihood of a successful outcome.

Enviah was founded by Lorissa MacAllister, a thought leader in the healthcare and design fields, and is a WBENC-certified Women’s Business Enterprise.
