The phlebotomist was lovely! Very professinal, knowledgeable and I didn't even feel the needle! Awesome!

I love the text message that I receive to check in. Makes it so much easier. More efficient, less waiting time. The place was very clean and the people that work there are very nice.

Denville is a convenient location. Check in is easy using the kiosk and the code received by email. At this visit, I was actually into the facility, taken in for services and out before my actual designated time. You can't beat that. The nurse was efficient and excellent. This is my preferred location for blood work.
