From the dudely side of the fence, I have not heard good things about Dr. Leis. Most of the FTM groups I'm a part of actively encourage avoiding him. He has apparently made transphobic remarks to patients and has said some really backward things in presentations. I'd be happy to go look back and send you screenshots of those conversations if you'd like.
If you're looking in the PA area, Dr. McGinn is well regarded and trans herself. Dr. Leis taught her, so I'd imagine aesthetically the results are very similar.
