He/She has then passed both the Written (Qualifying) and Oral (Certifying) Examinations given by the American Board of Colon and Rectal Surgery. Certification by the American Board of Surgery is required for all candidates prior to taking the ABCRS Certification (Part II) Examination. In addition to having proficiency in the field of general surgery and fundamentals of minimally invasive surgery, colon and rectal surgeons have acquired particular skills and knowledge with regard to the medical and surgical management of diseases of the intestinal tract, colon, rectum, anal canal, and perianal area. Colon and rectal surgical specialists also have special skills in the performance of endoscopic procedures of the rectum and colon and evaluation of the anal sphincter and pelvic floor using anorectal physiology techniques. A colon and rectal surgeon has been trained to deal with conditions such as, but not limited to, colon and rectal cancer, polyps, inflammatory bowel disease, diverticulitis, pelvic floor abnormalities, as well as anal conditions such as hemorrhoids, fissures, abscesses, and fistulas. Training in colon and rectal surgery also provides the specialist with in-depth knowledge of intestinal and anorectal physiology required for the treatment of problems such as constipation and incontinence. Board Certified colon and rectal surgeons are committed to the highest standards of care for patients having diseases affecting the intestinal system. - American Board of Colon and Rectal Surgeons



A native of Maryland, he grew up the son of a wonderful and excellent surgeon.  His father instilled in him the meaning of caring and concern for those that need medical help.

As a young man, he became an IFR certified pilot and loved the hands on aspect of working complex systems.  He used that desire to help obtain a degree in mechanical engineering from Drexel University.  He spent time working for GE Aerospace helping design space satellites.  He then worked for Kensey Nash Corporation as a research and development engineer.  He helped design implantable devices to aid in hemostasis after transarterial medical procedures.

He knew he wanted to do more.  He went to the University of Maryland Medical School and subsequently did his general surgery training at that same institution.  He then fell in love with colorectal surgery and did a fellowship at the University of Medicine and Dentistry of New Jersey.

He started practicing in 2005.  He is board certified in both general and colorectal surgery.
