The Union KC has a list of transgender resources for Kansas City residents, here is their promise:

There are a plethora of listings on the internet of professionals claiming to be LGBT friendly. While this can be reassuring to read next to a potential therapist, endocrinologist or surgeons name, it doesn’t always mean that there aren’t stipulations regarding their service or that it’s true at all.
We will not add a medical resource to our page unless we have a positive and successful experience reported by one of our members. If the resource has a mixed group of clients we will base our publication on the majority opinion. We want all of our members to have the best possible experience regarding their transition and will put the necessary efforts in to help make that a reality.
