“We have the latest and most sophisticated technology and devices. More importantly, we know how and when to use this technology in order to achieve the safest and best outcomes for our patients. From basic procedures in the office to our high volume of aneurysm surgery, we do them at the highest level. I try to help every patient develop a level of comfort that we are doing everything to achieve a good outcome, and that he or she cannot get better care anywhere. I look at the whole patient including risk factors, managing them medically when possible, or with minimally invasive or surgical treatment when necessary. It is important to me to remain highly accessible to other physicians also caring for the patient so that a more coordinated care can be provided.”
