- Doug Bacon delivers the entirety of the firm as we need it and offers guidance and judgment that is second to none. Lee Blum could not ask for anything more in an M&A partner, quarterbacking every transaction large and small with a diligence and passion that reflects the best-in-class approach the team brings every day.
- Kirkland & Ellis is quite simply the world's largest 'best in class boutique' law firm, offering a soup to nuts service for private equity sponsors, covering well the entire ecosystem of client needs - from fundraising to M&A to compliance - at a service level not matched by another firm in the world.
- Recommended for their responsiveness, fights for what really matters.
- Highly responsive. I'm sure they're working on other teams' deals, but it always feels like yours is their priority. They also have a massive team with a really strong breadth of experience; this is particularly true in private equity. If you have any questions around deal terms, precedents, fund terms, etc., they've seen it 1,000 times and you have comfort they're advising you on the back of real, lived experience.
- ‘Great depth, very responsive, highly proficient, great market knowledge, name rings out, aggressive, not afraid to mix things up’
- ‘Laura Sullivan is highly engaged in every deal’
