Philosophy of Care
Dr. Guevara is committed to the patient first and makes an effort to treat every patient as if they were a member of his own family. He also strongly believes in the idea that a patient-physician relationship is a partnership. Through this partnership, Dr. Guevara prioritizes translating medical issues such that patients feel empowered to make the right decision for themselves.
Dr Guevara specializes in treating diseases of the colon, rectum and anus. He has strong clinical interests in minimally invasive surgeries (laparoscopic and robotic surgery as well as transanal endoscopic microsurgery) as well as functional and pelvic floor disorders.
