I've seen Dr. Nicholson for 8 years and she's always been very encouraging and helpful even when treatment felt too difficult. The nurses were really nice, and the lab techs were kind and patient despite the fact that it's almost impossible to get blood from my veins on the first try. Everyone was nice and helpful

Yelena, and the nursing staff, are always wonderful when we are there. They always listen carefully to any care or concerns that we have and they ask a lot of questions about things that maybe we don't even think about, and then they always are careful to listen like we feel like we're not being rushed which is really nice so we appreciate them very much.
