Exhaustive Boutique Strategy Consulting Firms List

I've read a few threads related to this question, but I don't feel like I've been able to find anything approaching an exhaustive list of boutique consulting firms that mostly do true strategy work. Discussions of boutiques here have generally included economic consulting firms or firms that focus on some aspect of operations. What I'm looking for is a comprehensive list of all the firms that take fresh college graduates as analysts and offer a true consulting experience at a smaller firm the same way a regional boutique bank offers true investment banking experience. Here is a list of all the firms I know of that I believe fall into in that category:

Kaiser Associates
Marakon
Kurt Salmon
Putnam Associates
ZS Associates
OC&C
Mars & Co.
Arthur D. Little
Simon Kutcher and Partners
The Cambridge Group
Keystone Strategy
Altman Vilandrie
Delta Partners

All contributions are welcome.
