Care Philosophy

This content was provided by Dr. Flannery Jr "Patient satisfaction is one of my highest priorities.  Along with my dedicated staff, I persistently seek to offer the highest quality patient care experience.  I conduct my appointments with the personalized care and attention that I would expect for my own family.  I take the time to carefully listen to my patient's symptoms and concerns and then recommend the best treatment options for their condition.  Most importantly, I am considerate to always include my patient's individual needs in the decision making process.  In addition, I not only treat the clinical issue at hand, but counsel patients on ways to lead a healthier lifestyle.
