Yassss!! This is my girl! She has helped me get my hormones in check and by so, helping minimize my anxiety SO much that it's almost non existent and helped me drop 35 lbs (without weight loss meds) since Thanksgiving. She has been nothing but a godsend and I'm so thankful!

The owner is the provider! Chassidy is amazing and so passionate about what she does. She truly cares about you and how you feel. She wants to help you feel the best you can in life. I started hormone therapy about 18 months ago and it changed my life. I was miserable with hot flashes, brain fog, low energy and just felt like crap most days. After 6 weeks of meds I felt like a whole new person!!! All my symptoms either went away completely or all most completely. I cannot imagine ever not doing this program. Chassidy is so passionate about listening to how you feel and fixing the problem. I highly recommend Peak Performance you won’t regret it!!! Make an appointment right away!!!

Chassidy genuinely cares for her patients, she’s very knowledgeable and doesn’t give you anything you don’t need, I would recommend anyone who cares for their health and wellness to partner with her, her staff is amazing and kind, it’s a joy to have a practitioner who listens and communicates, and doesn’t just treat you as a number!

Went in kinda skeptical and to my surprise with ZERO working out, no diet change, simply “testing” what the treatment alone was capable of, it transformed my body and I’ve felt great.

I had an excellent experience with HRT therapy at this clinic and couldn’t be more impressed with the level of professionalism I received. From the moment I walked in, the staff made me feel comfortable, respected, and genuinely cared for. They took the time to listen to my concerns, thoroughly explain the process, and answer all of my questions without ever making me feel rushed.
The providers are incredibly knowledgeable and attentive, creating a personalized treatment plan that truly fit my needs. Throughout the entire process, they maintained clear communication and followed up to ensure everything was working well and that I was feeling my best.
The clinic itself is welcoming, and very well-organized, which added to the overall positive experience. It’s clear that they prioritize both patient care and professionalism at every level.
Since starting HRT therapy here, I’ve noticed a significant improvement in my overall well-being, energy levels, and quality of life. I would highly recommend this clinic to anyone considering HRT—you're in caring, capable hands.
