flat foot surgery

I am in need of major surgery for my painful flat feet. I have gotten many opinions, and I evidently need the following procedures:
Evans osteotomy
Calcaneal osteotomy (to move the heel)
gastrocnemius recession (gastroc release)
Fusion of the first TMT joint at the mid-foot
FDL transfer

I am in the process of choosing a foot surgeon. Has anyone here gone to any of the following doctors:
Dr. David Thordarson at Cedars Sinai in Los Angeles
Dr. Jonathan Deland at the Hospital for Special Surgery in NYC
Dr. Martin O'Malley at the Hospital for Special Surgery in NYC

If you have had experience with any of these doctors, I would be very grateful if you please respond to this post. Any information would be much appreciated. Thanks.
