About Us

KPS Cardiovascular Surgery has been the premier thoracic and vascular practice in the North Houston area for more than 25 years. Over these years,we have made patient care our primary focus, maintain and expanding patient and referral relationships. Our practice currently serves 8 acute care hospitals in the North Houston suburbs of Cypress,Tomball,Spring,The Woodlands and Conroe. All of these acute care hospitals maintain busy cardiac,thoracic and vascular programs. Our practice has the unique ability to deliver world renowned medical center care while still maintaining close patient relationships in areas close to the patient's home.

As our area has grown, so has our practice. Originally started by Clifford Kitten MD, Fred Pauling MD, and Daniel Stroud MD in the early 1990s, our practice has grown to include Lucas Duvall MD and William Sweezer, MD. All surgeons are board certified in thoracic surgery, maintain various administrative roles within the hospitals, and are well respected in the community. They work in a cohesive manner to cover multiple hospitals and office settings. Our group currently does over 1000 cardiac procedures annually as well as hundreds of vascular and general thoracic cases.

Our hospital affiliations

Covering multiple sites would not be possible without excellent relationships between the physicians and Physician Assistants. Our practice currently employs three Physician Assistants who function in the surgical, hospital and outpatient roles. Our Physician Assistants are experts in endoscopic vein harvesting, with thousands of cases between them. In addition to vein harvesting and assisting in cardiac cases, they provide first assist roles in all thoracic and vascular cases,perform intensive care procedures, and manage pre, intra,and postoperative care for all KPS patients.
