In patients' words

"ProHealth does NOT give their physicians the option to leave appointments open for immediate care. If a patient feels a need to see their primary physician quickly it is impossible..."

"Dr. Nelson takes a lot of time to listen to you and explain everything. He is great!! When other doctors couldn't help me with my cholesterol, he figured out a way to lower it."
