Dr. Maniscalco, Dr. Davis, Dr. Walkes Cardiovascular Surgeon

We are pleased to announce new procedures to help with unsightly and potentially painful venous concerns. We offer minimally invasive procedures for the treatment of symptomatic varicose veins in addition to cosmetic therapies to patients who have spider veins of the legs and arms and wish to improve the appearance of their skin.

Our mission is to provide the people of Southeast Texas with the most comprehensive and progressive cardiac, thoracic and vascular surgical services – delivered with compassion, integrity and dignity – emphasizing accessibility, dependability, patients’ rights and community commitment.

A tradition of excellence has earned our doctors a national reputation. In addition to surgery, we participate in conferences and seminars to teach other physicians our progressive surgical techniques.  All of our surgeons are board certified in their area of specialty.

We have over 30 years of surgical expertise; handling complex problems of the heart, lungs, and peripheral arteries.  We look forward to working with patients to improve quality of life and prevent the disabling complications that arise from these disorders.  You can be confident that our understanding of anatomy and physiology of these problems far surpasses other physicians providing these same services who do not share a similar surgical background.

Who better to trust your veins to than the doctors your trust with your heart.


Physicians Assistants:
Our practice employs two Physicians Assistants; Andrea Colburn Jack Lai, PA-C and Andrea McNiel, PA-C.  It is very likely a Physician Assistant will see you in the clinic and for your vein ablation procedure. These individuals assist the physicians in the operating room as well as the clinic.  They are a huge benefit to our physicians, and more importantly, to our patients.  With five providers carefully monitoring your care, you can be assured you will have the best outcome possible for your surgery.
