I had not seen tammy since 2016-2017 when she cared for me at Waukesha Memorial. She was spot on in helping me fight this heart disease for 45 years. She is excellent.

Tammy went thru Rx's and gave a wonderful explanation of all of them to my daughter and I. Best NP I have ever seen! Advised re: Watchman.

All of my providers have gone above and beyond to get me ready for the big surgery I'm having.

My sense is that I received a high level of care during this visit. It is my first contact with this provider & I felt confident in her ability to assist me. Thought she represented herself & ProHealth in a very professional fashion.

This was my first time with Tammy L. Johnsen. She expressed concerns with the side effects of one of my medications during our discussions she consulted three times with her superior.
