Dr Serna is competent, thorough, caring, and a good listener. She wants her patients to know and understand about their illness so she takes the time to explain or answer questions. I love receiving a printed summary of my visit with all the pertinent information on it.

Concierge or membership medicine, is an alternative practice model. It is based on a relationship between a patient and a primary care physician in which the patient pays an annual fee or retainer. Doctors limit their patient panel in order to ensure direct availability and adequate time for each patient. These extended, unrushed visits enable physicians to spend meaningful time with patients, build relationships, and provide more comprehensive, proactive care than in traditional practices.
