We visualize success and make it happen.

We operate with urgency; patients can’t wait.

Always Growing

We are change-makers, and we never stop in our quest to advance therapies for patients in need. For us that takes a number of forms — we stay abreast of the most recent Sigilon science at our Sigilon Monthly Sessions, where a team member presents their findings and cross-pollination of ideas is encouraged; we also meet up informally, around the weekly Friday breakfast or in our collaboration hubs outside the lab. In this way, we’re always inspiring one another and advancing science that matters.

Never Losing Sight of Our Purpose

We’re at Sigilon to make a difference for patients, and that is front and center in our day to day work. We host patients and caregivers at our offices to learn more about the disease areas we aim to treat. And we stay engaged with the broader community, from organizing a fundraiser to send young people to the New England Hemophilia Association Family Camp, to sponsoring rare disease awareness efforts.

Enjoying Our Relationships

From our Sigilon running team to occasional yoga outings to escape rooms and offsite retreats, we really enjoy our teamwork in all forms. We are a close-knit team with an upbeat atmosphere, and it shows in our productive science — a true team effort.

Life at Sigilon

We have an amazingly collaborative team; we really like each other and this makes working together enjoyable.
