We waited almost a year to see Medina and it was worth the wait. We are finally making progress and getting some testing done. He was so kind caring and explained things so well.

Very informative and the provider was very knowledgeable and understanding.

We were blown away by his knowledge, level of understanding, and plan going forward. We are so thankful!
