Helena,
I am glad Dr. Z is on your list of options. My advice to you and your friend. Reach out to Dr. Zavalza.
His email is: Juan Francisco Zavalza Gonzalez <dr_zavalza@hotmail.com>; add him to Skype and reach out to him. Have a Skype interview with him. Have your list of questions ready for him to answer for you!
It was the Skype conversation that made me lean towards him and not the other surgeon I had in mind. After my Skype convo w him, I immediately made my deposit. '
