"Having a concern about a colorectal condition or a general surgical problem can be embarrassing and a scary time. Having to try and navigate the healthcare system to find someone you can trust and find a solution can add to that stress. I understand this having dealt with many patients and people close to me with similar issues. I will put you at ease, assess you meticulously and provide you with an honest opinion."
