  • Biography


    The most important approach to treating patients is recognzing that each patient is different and presents their own unique circumstances. I take the time to listen to the patient and work with patients to base treatments tailored to what is best for the particular medical, social, and financial situation. I remind patients that they are in control of their healthcare and I am just here to guide them.
