First time visiting this practice and Dr McWilliams. Front desk staff amazing other staff members were pleasant as well and helpful. Dr McWilliams is very kind, take the time to listen to your concerns and answers any and all questions, never felt hurried or rushed, or that anything I was asking was too much much. Dr McWilliams listen to all my concerns and and gave me his recommendations on how to move forward with some issues I was having and we will do a recheck in 3 months. I I absolutely recommend this practice and this doctor, after having been to many specialists and doctors over the span of my lifetime, I had a very pleasant experience and felt like my rapport with Dr McWilliams was one that I would want to continue and have him oversee any future issues that I may have that may occur. I never once felt like rushed or hurried along. Highly recommend this doctor and this practice.
