Get to know Mather's Pelvic Floor Therapist, Annie Neisen, DPT, PT, WCS 🖤

Q) What inspired you to pursue a career in health care?
A) My path to becoming a physical therapist started when I was 12 years old and going through rehab following my first of many knee surgeries. Having a career that allowed me to help people, like I had been helped in my rehab, was important to me. I pursued an undergraduate degree in psychology because I recognized what a huge aspect our psychological health has on our physical health. I was inspired to learn more about pelvic health rehab, including becoming a certified s*x educator and board-certified women’s health specialist, because it allowed me to integrate my passion for women’s health, provide vital health and s*x education, and use my physical therapy skills.

Q) Is there a book, podcast, or mentor that has had a significant impact on your professional life?
A) A podcast that really influences how I treat patients is called Unreal Results. Anna, the host, has really changed how I approach treating the body. She calls it a whole-organism approach that considers the interplay between different systems in the body and helps identify the driving factor to dysfunction and symptoms.

Q) Is there a quote or motto that you live by?
A) “If you want the rainbow, you have to put up with the rain,” Dolly Parton. There isn’t any way to avoid the ups and downs in life; they go hand in hand. Even if I’m not always successful, I try to find beauty in the hard parts of life.
