Everybody was great (for a procedure nobody enjoys preparing for)! Friendly, clear information, quick, nice facility. Loved my nurse Elena and all were reassuring.

In the past I had significant difficulty with the prep until now. This experience was different. Apart from the reduced liquid intake I was given medication for nausea which helped a great deal. Dr. Lee and the entire staff were kind, thoughtful and focused. Highly recommend.
