David provided my husband with excellent care. His passion for what he is doing is evident. He helped us to navigate pain management changes better - and under very fluid/moving conditions. David communicated effectively when oncology, GI and neurosurgery had to abruptly change course due to test results that had just come in. He kept everyone calm and informed as he received updates. After completing colonoscopy prep, my husband had to be on strict bedrest, cancel the procedure, and change the next steps - several times. He was on top of medical changes, alert to my husband's various needs, and had excellent communication with us and the internist, and all involved. He was positive, proactive, personable, and so easy to talk to.
