We pride ourselves in establishing a definitive diagnosis, as well as providing outstanding preoperative, operative, and postoperative management for a variety of surgical conditions.

Any surgical procedure or consultation can be a stressful event in your life. We believe that this stress can be eliminated through good communication. We want our patients to be informed and also active in making treatment decisions. We will meet with you and your family to explain procedures and recommend treatment plans. We will also review the alternatives, discuss the associated risks and benefits, and answer all of your questions.

Gallbladder and Biliary

If you have severe gallbladder issues, your doctor may recommend surgery. Gallbladder removal is known as a cholecystectomy and this procedure can be performed using minimally invasive techniques. With laparoscopic surgery, your surgeon can remove your gallbladder through very small incisions, making the procedure virtually scarless.

Hernia & Abdominal Wall Reconstruction

Reconstructing the abdominal wall is a complex procedure designed to correct defects or weaknesses. These openings may be naturally occurring (which is usual), or may stem from prior surgery, traumatic injury, hernia recurrence, or infection. Robotic-assisted techniques can minimize the recovery time and postoperative pain.

Skin and Soft Tissue

We perform a wide variety of surgeries on the skin from removing skin cancers to rare tumors. Our Surgeon also removes tumors that can grow just below the skin, such as fatty tumors, or tumors that arise in muscles or other soft tissues. We also treat more complex skin or subcutaneous infections, such as necrotizing fasciitis. Various skin closure techniques are used, including skin grafts and vacuum-assisted closure devices.


We offer comprehensive evaluation of breast masses, abnormal breast discharges, breast pain, and abnormal mammograms. General surgeons perform a majority of all non-cosmetic breast surgery from lumpectomy to mastectomy and lymph node procedures, especially in evaluating and diagnosing breast cancer. . We work in collaboration with medical oncologists, radiologists, radiation oncologists, and plastic surgeons to ensure a multidisciplinary strategy for our patients.


Our surgeon treats a variety of problems of the colon, rectum and anus—including benign conditions, such as hemorrhoids, as well as cancer. Dr. Irene B Houari has vast experience treating common and rare problems of the colon, rectum and anus. As part of our integrated, multi-disciplinary approach to your care, we work closely with specialists across the board, as well as primary care physicians, radiologists, gynecologists, urologists, and nutritionists, to develop an individualized and comprehensive care plan.


We collaborate closely with gastroenterology physicians. If surgery is recommended after an initial evaluation, we work together to help you determine what surgical approach—if any—is the best choice for your condition.
