Are the doctor's skills more important than being board certified?

[Andgy]

Is it important that a doctor doing gynecomastia surgery be a board certified plastic surgeon?

I have read that some doctors who are trained in "aesthetic medicine" could also do a good job, having had many years of experience in liposuction and gynecomastia surgery.

On the other hand, a board certified plastic surgeon may be good in other areas of plastic surgery but their speciality or experience may not be extensive in gynecomastia surgery.

Could anyone kindly comment?

It is highly recommended that you seek out a board-certified plastic surgeon who specializes in gynecomastia surgery. 
Board certification is a symbol that a doctor has undergone additional training in their specialty, has proven a high level of expertise in that specialty, and is, therefore, better qualified to practice in that specialty compared to a non-certified doctor.
