He was able to recommend an OB for me and most importantly he kept it real! I’ll definitely be back next week for my follow up!! The gentleman at the front desk was awesome, answered any questions that I had and when he had to draw my blood he was perfect. I didn’t have to poked several times, he got it on the first try.
