Hi Alli. I'm not too sure about being specific as I'm new on here but I'm sure one of the other ladies will be along soon who can answer.
Are you worried about how competent they are? You can ask the hospital how many cvs procedures she/he undertakes and how often and also what their % of mc risk is. I think the norm is 1-1.5% but the hospital I went to has a massive maternity unit and their's was 0.7% due to the high number they perform.
