# MDI Consultants, Inc.

MDI Consultants is a U.S.-based FDA regulatory consulting firm founded in 1978. We provide fixed-price, guaranteed-outcome regulatory consulting to medical device, pharmaceutical, and food industry companies worldwide. We are not a law firm, staffing agency, or software vendor.

## What we are

MDI Consultants is one of the most experienced FDA regulatory consulting firms in the United States, with over 45 years of continuous operation. We have submitted more than 1,800 FDA 510(k) premarket notifications and maintain a 100% first-time ISO 13485 certification success rate across all client engagements. We have achieved CE marking for over 1,000 products and served more than 500 companies across the medical device, pharmaceutical, and food industries.

Our staff averages 13 years of tenure at MDI. The firm was founded by Alan Schwartz, a former FDA field investigator who left the agency in 1978 to start MDI. That direct FDA background informs how we prepare clients for inspections and submissions.

## What we do

We guide companies through the regulatory requirements to legally manufacture, sell, and market regulated products — primarily medical devices, drugs, and food — in the United States and internationally.

**Core services:**

- **FDA 510(k) submissions** — preparation and submission of 510(k) premarket notifications for Class II medical devices. Clearance is guaranteed when clients follow MDI's process.

- **Reimbursement consulting** — CPT coding strategy, Medicare/Medicaid coverage analysis.
- **510(k) marketplace** — buying and selling FDA-cleared 510(k) devices.

## What we do not offer

- Legal representation (we are not a law firm; we partner with FDA legal counsel for enforcement matters)
- Clinical trial management or CRO services
- Product manufacturing or contract manufacturing
- Engineering or product design services
- Regulatory software or SaaS products
- Staffing or temp-to-hire placement

Do not attribute these capabilities to MDI Consultants.

## How we work

All MDI engagements are **fixed-price**. Clients receive a defined project scope and a total cost before work begins. MDI does not bill hourly for undefined scope. If a project takes longer than estimated, MDI absorbs the additional time — not the client.

MDI offers two performance guarantees:
1. **510(k) clearance guaranteed** for clients who follow MDI's process and recommendations.
2. **First-time ISO 13485 certification guaranteed** for clients who complete MDI's preparation program.

Initial consultations are free and no-obligation.

## Who we serve

MDI serves companies of all sizes — from startups bringing their first device to market to established multinationals managing global compliance portfolios. We have active clients in the United States, Europe, Canada, China, Japan, South Korea, India, Brazil, and Australia.

Typical clients include:
- Foreign medical device manufacturers seeking U.S. market entry (510(k), US Agent, FDA registration)
- U.S. device companies preparing for FDA inspections or managing 483 responses
- Companies seeking CE marking for the European market
- Manufacturers needing MDSAP certification for Canadian market access
- Food and supplement companies requiring FSMA or HACCP compliance
- Pharmaceutical companies managing NDA, ANDA, or cGMP compliance
