I recently had a colonoscopy done which is not very fun. the prep is the part. I had to have this because my father had colon cancer and even though im in my 40's I'd like to know if there's a problem beforehand. Dr Vogel and the crs staff at rochester hills were VERY professional and helpful. Everyone from the receptionist to the doctor treated me great. I would recommend anyone having this procedure done, to go here because of the awesome bedside manner. I really thought I would run into some attitudes like with other offices that make me steer clear of them, but all i got was courteous, knowledgeable, professionals! Thanks CRS for making an uncomfortable problem a pleasant one. All of the docs are great because i saw another first, (my prep didnt take the first time-follow it to the letter-believe me!) Dr Hain was awesome too! Dr.Vogel is just the BEST !!! TY CRS!!!
