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.

Dr. Serna is a great listener. I lean towards homeopathic medicinal solutions, and she does a fantastic job understanding my goals, educating me, and finding solutions that work for me and my family.
Dr. Serna has put together an exceptional team that is dedicated to the individual patient. She has the drive to balance both her personal and professional life to near perfection. She has put family back in the doctor’s practice. The staff follows her lead in caring and being concerned for the individual patient. I have watched her grow into a professional’s professional. I highly recommend her and her team to anyone.

Access Our Virtual Waiting Room

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.
