I can't comment on Dr. Avellino, however you'll probably see a lot of men recommending a surgeon who has done a large number of these procedures (100+ per year maybe?). Most of the high volume surgeons will have the designation "Center of Excellence" next to their name on the Coloplast and/or Boston Scientific AMS provider lists.
I would look for providers near you, prioritizing Center of Excellence designation. Then, start searching this site for their names. As an example, I found Jared Bieniek, MD near Hartford, CT on the Coloplast site and I found one very positive review of him on this site. I have no personal knowledge of his skills though - this is just an example. Dr. Avellion's website doesn't even mention this procedure for example - to me that's a bit of a red flag that they may not focus on this procedure.

https://www.edcure.com/us/en/find-a-specialist.htmlI live in Denver and I travelled to Houston to see Dr. Clavell. It was totally worth it to travel for me, so don't get too tied into the idea of doing this locally. It is very doable to travel. For example, Dr. Eid in NYC is probably not too difficult to get to and he's one of the legends in the field. The piece of mind you get from reading many glowing reviews about your prospective surgeon is priceless (but no guarantees obviously).
