DFW gastric bypass revision doctors?

Hi I've been looking around these forums for advice on DFW based gastric bypass revision docs. My original was done by Dr. Alexander in 2000. Any advice would be appreciated. Whose was yours with? Anyone to avoid? 

I had a revision from VGB to RNY and use Dr. James Davidson. He also did my sister lap band to RNY.

My surgeon is Dr. David D. Kim.   I didn't have a revision but he does them and his patients are very successful.   He also has a support group each month for his patients and we also have 2 other chances for support each month along with a facebook support group for his patients only.   He is a amazing doctor, surgeon, and person.    Good luck in your decision.

 

Hugs and blessings ~~~ Vivian
