Meet Mullins McDonnell.

Exceptional legal work backed by authentic human commitment.

Three seasoned defense attorneys chose to build something better. That’s what we call a good start.

Rob Mullins, Jenna McDonnell, and Mike Sullivan built Mullins McDonnell around a straightforward belief: Doing good work and being good to work with aren’t mutually exclusive.

Together, we handle complex, high-stakes matters with senior-level skill while maintaining relationships and being responsive without sacrificing efficiency. Our practice combines decades of experience serving the nation’s largest companies with the personal attention and operational agility that only a boutique firm can provide.

Principles in practice.

What guides every decision, every case, and every client relationship—every day.

Authenticity.

We believe legal work is fundamentally about human relationships. Good neighbor approachability means being accessible, responsive, and invested in your success. It’s how we build the trust that creates lasting partnerships.

Commitment.

Doing right by our clients isn’t just good business. It’s who we are. Our clients don’t just hire us for individual matters. We provide ongoing support backed by a lasting relationship.

Agility.

When urgent legal matters arise, you need more than expertise. You need responsiveness. We respond immediately because we don’t have layers of bureaucracy slowing us down. Speed and accuracy work together when you have the right structure.

Dedication.

Doing the right thing when no one’s watching isn’t just a value statement—it’s our competitive advantage. We put client interests first because that’s how we’re built. Integrity drives every decision, from case strategy to billing practices and beyond.

Excellence, executed.

Enhancing human judgment with technology.

We are leveraging AI to enhance our capabilities, allowing us to focus more time on strategy and client relationships.

Leading with experience while developing the next generation.

Every case gets partner oversight from start to finish, but we’re also building the next generation of defense attorneys. Our junior attorneys work directly with partners to combine fresh perspectives with seasoned experience.

Going the distance.

Showing up isn’t a sometimes thing. It’s everything. Balancing formidable advocacy with civility to achieve the best possible result is who we are.

Build something better with Mullins McDonnell.

With more than 50 years of combined legal experience, we know what a successful career in corporate defense looks like: meaningful work, senior-level mentorship, and a practice that’s built around people, not on top of them. We’re looking for attorneys and staff who want to invest their skills somewhere that invests back.
