I don't know those surgeons personally, but only one of them is CRS trained, and he is relatively new in practice. For the surgical oncologists listed, I don't know if any of them specialize in colorectal surgery and do a large volume of complex laparoscopic colon surgery.
I believe that some surgical oncologists are excellent at colorectal surgery, but it is very much dependent on volume and experience. If it's a surgeon who does mostly pancreatectomies, but also does an occasional colectomy for cancer, he/she may not offer the same surgery that a full-time colorectal surgeon can offer.
I'm also not sure how critical it is to use a "cancer center." Sometimes, these are great, but other times can be gimmicky (not always affiliated with a university, centered more on profit, etc), and are not necessary for all colon cancers. There are a lot of good colorectal surgeons in Atlanta that aren't specifically associated with one, including
this group which sponsors a fellowship.
