    Kathy Byrne, CRNP has consistently provided me with outstanding care over the years. She's the gold standard for listening skills and compassion; she is clinically extremely competent. I ask her about the latest clinical trials and she is up-to-date and explains in lay language the status, who qualifies and whether I would benefit. I feel fortunate she is my clinician. I have not be able to get this level of specific knowledge and specific care from my cardiologists. Thank you.
