I agree Dr. Hamersma has conservative views only know this because I engaged him in conversation, but disagree about him withholding anything based on non-medical beliefs. There was a particular controversial drug I wanted to try, and although his opinion was conservatively based, he honored my request. If you are looking for an honest, ethical, to the point doctor, I’d recommend him!
It should be noted that Dr. Hamersma holds very conservative religious beliefs which he uses as his reason to not prescribe birth control no matter the reason. So do not engage with him as your PCP if those healthcare rights apply to you, as he will refuse those services to you.
