Welcome to Colorectal Surgery Associates of Kansas City

With more than 90 years of combined experience, Colorectal Surgery Associates is Kansas City’s trusted leader in colon and rectal care. Founded in 1991, our practice continues the legacy begun in 1979 by Drs. W. Edwin Conner and John W. Heryer, pioneers in colorectal surgery.

Designated a Center of Excellence by Menorah Medical Center, we are the referral choice for GI specialists across the region. Our board-certified surgeons deliver cutting-edge treatments for diseases of the colon, rectum, anus, and intestines, using the latest surgical techniques.

We are committed to personalized care, clear communication, and building strong doctor-patient relationships that lead to the best outcomes. We are a team of robotically trained surgeons, and specialize in Da Vinci surgery for all types of colorectal ailments. When colorectal surgery is necessary, we believe it should be precise, state-of-the-art, and minimally invasive to reduce healing time and patient discomfort.
