Antioch Request an Appointment“Exceptional cancer care requires that a physician understand not only a patient’s complex medical issues but appreciate the impact an illness has on his or her life and loved ones. As a physician I must be a guide for patients through harrowing times and promote the understanding of not only the best medical recommendations but how those recommendations affect the individual.”

Celebrating Excellence at Epic Care! 
Sep 10, 2025Dr. Seaver was excellent at explaining my mother's medical condition in a clear and understandable way. What stood out the most was how much time she took to listen and address all of my concerns. There was never a sense of being rushed. Dr. Seaver showed genuine empathy and care throughout the visit, which made me feel comfortable and well taken care of. Highly recommend!
