Mass General Brigham is the largest private employer in Massachusetts and one of the biggest integrated health systems in the country. It runs Massachusetts General Hospital, Brigham and Women's Hospital, several community hospitals, and a research enterprise that pulls in roughly $2 billion a year in funding. A system that size buys constantly: medical and surgical supplies, lab reagents, IT and software, facilities and construction services, food, environmental services, staffing, and professional services. If you sell any of that, the question is how to get in the door without getting lost in a procurement function built for incumbents.
Here is what the registration process actually looks like, what changed in 2025, and which certifications matter.
Start with the supplier/vendor information pageMass General Brigham keeps a public supplier/vendor information hub at massgeneralbrigham.org/en/supplier-vendor-information. That page is the front door. It points small and local businesses toward the procurement team and lays out the two separate tracks you need to understand: getting recognized as a potential supplier, and getting credentialed to physically enter clinical space.
Those are different things and people conflate them. Being a registered supplier means MGB's sourcing and category managers can find you and route work to you. Credentialing is about badge access to patient care areas. You can be one without the other depending on what you sell. A software vendor may never need a badge. A medical device rep who details surgeons in the OR needs both.
The Impact Purchase Program, launched in 2025In 2025 Mass General Brigham introduced the Impact Purchase Program (IPP). It is the system's effort to direct more spend toward local, small, veteran-owned, and disability-owned businesses. The framing is deliberate. After the broad pullback in corporate "diversity" language across 2025, MGB anchors the program in local economic impact and small-business growth rather than identity categories alone, which is where most large institutional buyers have landed.
What the program offers, per MGB's own description, is practical:
- Access to departments and projects that fit your capabilities, so you are not cold-pitching a 80,000-person organization.
- Introductions to larger contractors for subcontracting opportunities. This matters for construction and facilities work, where the prime holds the contract and the diverse-supplier dollars flow through Tier 2.
- Guidance on registration, documentation, and getting "bid ready." That last phrase is the tell. MGB will help you assemble what a hospital procurement team needs to see before they can route real work your way.
The program contact listed by MGB is dshahin@mgb.org. That is the email to use if you want to understand IPP eligibility and how to be considered. MGB has not published a numeric diverse-spend target or a hard set of certification gates for IPP, so confirm current eligibility directly rather than assuming it mirrors a federal set-aside program.
Green Security credentialing for clinical accessMass General Brigham contracts with Green Security for vendor credentialing. If your reps need to enter patient care or clinical areas at most MGB facilities, they have to register with Green Security and obtain a badge before they show up. This is non-negotiable at the door.
Plan for it early. Credentialing typically means proof of insurance, immunization and health records for the individuals entering clinical space, training modules, and a background check. None of it is hard, but it takes time, and a sales motion that ignores it stalls the day your rep is turned away at the front desk. If you sell devices, implants, or anything that involves being in a procedure room, treat Green Security registration as a parallel workstream to your commercial pitch, not an afterthought.
Which certifications helpMass General Brigham has not published a rigid list of certifications it requires. That is normal for hospital systems, which lean on category sourcing more than formal set-asides. Certification still does real work for you here: it makes you findable, it lets MGB count your spend toward its small-business and impact goals, and it signals that a third party has already verified your ownership and your books.
The credentials worth holding for an institution like MGB:
- NMSDC MBE certification for minority-owned businesses. This is the platinum standard in the private sector. As of May 19, 2025, the Greater New England Minority Supplier Development Council stopped processing applications and the National Minority Supplier Development Council now manages MBE certification directly. If you are weighing it, our NMSDC certification guide walks through what it covers and who recognizes it.
- WBENC WBE certification for women-owned businesses, recognized across corporate procurement nationally.
- Veteran-owned and service-disabled veteran-owned status, which maps directly to one of IPP's named priorities.
- Disability-owned (DOBE) certification through Disability:IN, again a named IPP priority.
- Massachusetts SDO certification through the state Supplier Diversity Office, useful because MGB operates in the Commonwealth and many local and public-adjacent buyers cross-recognize it.
Holding the right certification before you approach IPP shortens the "get bid ready" conversation, because the documentation MGB would otherwise help you assemble is largely the same paperwork certification already validated.
What MGB actually buysMatch your pitch to a category. Hospitals of this scale spend across medical-surgical supplies and devices, pharmaceuticals and lab, capital equipment, IT and clinical software, construction and facilities, environmental and food services, staffing and clinical labor, and professional services like legal, consulting, and marketing. Service businesses often have a faster path than product vendors because clinical product onboarding runs through value-analysis committees and group purchasing contracts. If you are a diverse supplier in flooring, IT support, translation, fleet, or professional services, your route in is usually a facilities or administrative category manager, not the clinical supply chain.
A realistic sequence- Read the supplier/vendor information page and identify the category your offering fits.
- Email dshahin@mgb.org to ask about the Impact Purchase Program and how to be considered for your category.
- If your people need clinical access, start Green Security credentialing in parallel.
- Get the certification that matches your ownership, so your spend can be counted and your verification is already done.
Other large health systems and corporations run similar programs, and the same certifications travel across all of them. You can see how MGB compares to other institutional buyers in our corporate program directory.
Next stepIf you do not yet hold the certification an institution like Mass General Brigham will recognize, that is the first lever. CertifyAll captures your business details once and prepares the certification applications you qualify for, so you spend your time on category conversations instead of paperwork. Start there, then point your finished credential at MGB's procurement team.
