DS Switch in Mexico

Can someone tell me about their DS experiences in Mexico. I've heard some good things about Dr. Lopez and was wondering if anyone else had a good DS doctor in Mexico they could recommend. 

I did a sleeve in 2010. Went down to 140lb.  I regained back about 30 pounds. I know in the near future I need a revision. I had a lap band at one point and converted to sleeve. I am now 170lb. 

I would like to go back down. After conversing with a couple surgeons I know my 2 choices are either DS or RNY. My sleeve surgeon tried to talk me into an RNY but I am hesitant and will take my time before I convert. So I'm looking at all my options.

Hello Lorna, I had my surgery done with Dr. Ponce last year (2013) I think you should consider having your surgery with him he is the best surgeon I`ve had.  Also his Patient Coordinator (Trish) was very friendly, kind and helpful.  Would you like me to give you her contact number so you and talk to her and consider haveing you surgery done by Dr. Ponce ? If you do Please send me an e-mail and I give it to you. I will wait for your e-mail so we can chat :)) I`m so happy with my sugery and my life was changed I Thank Dr. Ponce and Trish.  

I had a duodenal switch done in 2010 by Dr. Ungson in Hermosillo MX. He was wonderful and my experience was great. I originally had a vsg done in 2007 by Dr. Kelly in Tijuana MX and I didn't lose all the weight I wanted; I even began to regain. My original weight before all surgeries was 255. I now weigh between 133-135. I'm now about to have plastics done to remove all my hanging skin.
