I have used Colleen Van Der Laan and Shelley Sjaarda and I

them both! They are each others back up mw and are based at Waterford. They both seemed comfortable to go with whatever I chose, however I birthed all 3 kids at birth centres (2 @ Waterford, 1 @ River Ridge) so can't comment on a hospital birth. However after having Ollie I was transferred to the hospital due to fully retained placenta and Colleen seemed to interact really well with the hospital staff there.
Hope that helps?
Oh, congratulations by the way and best of luck with your search
