He was very kind and understanding. He was doing a procedure on my leg and I freaked and he stopped. He is one of a kind for a Dr. He said he would try and figure out how to do this procedure in another way so I dont freak again. I told him " they need to get Nitrus in their office" that helps tremendously, or at least for me it does. The previous Trama I have gone thru has caused alot of problems.

I have been two dozens of doctors over the years with my vein issues, and Dr. Marshall is the first that I feel confident of his abilities and his application of his work and studies. I really like his whole crew too. I'm happy to be under their care. Thank you!
