I believe care must be customized
to each patient because the practice
of medicine is not a “one size fits all”.

With all of his Louisville patients, Dr. Evans works hard to ensure that they have a complete understanding of their treatment options, average outcomes and potential risk and complications of each procedural and surgical treatment type.
