In addition to his busy practice as a cardiothoracic surgeon he has taken a very keen interest in caring for patients suffering from vascular diseases of the lower extremity including critical limb ischemia (CLI) and chronic venous reflux (CVR). He understands the devastating complications that lower extremity amputations cause and will go beyond what other interventionalists may think possible regarding limb salvage. As a surgeon Dr. Davis brings an unbiased approach to treating vascular disease as he is able to objectively deal with problems both from a surgical as well as interventional perspective, thus affording patients the best opportunity for complete revascularization.

​

Over his career, Dr. Davis has developed minimally invasive strategies for limb salvage that can be performed without surgery in a safe and comfortable setting for patients. Dr. Davis has completed over 15,000 of these cases, most very complex and time-consuming. In the last three years he has performed over 1200 of these procedures in his office-based lab (OBL) in Kingwood, Texas. In the OBL, he and his staff have consistently demonstrated quality and compassionate care. Patients are given the attention they deserve and are treated like family.​
