I had been looking for hormone health something more natural a bio identical hormone since my body was breaking out in a rash from the synthetic hormones I was taking. I googled and found Optimize U and called right before closing time and spoke with Kelly on the phone and she was so down to earth and friendly and knowledgeable about hormones and weight loss and she listened to me babble on about everything I had going on and answered all of my questions way after closing time. I felt so heard and understood that I knew I found my place because they was going to get me in great health .I booked my appt for a few days later . I met my PA-C Jason Black and wow he is Amazing too .My appt with him lasted a hour or more he listened to my history and we came up with a game plan on how we was going to make me feel amazing again. He really knows his stuff. I think that’s the first time I had someone listen to me and try to help me through this next chapter of life and them be so compassionate about what they do and how they will and can help. I am feeling better and getting healthier from their guidance and losing a little bit of weight . Now when I go into the office for red light therapy Jason and Kelly they say hi and always ask me how I’m doing and if I have a question they will take time to answer it .Trust me when I say this you can’t find a better place to go for hormone health and weight loss than this because I have tried .

I switched to Optimize U after a bad experience with another clinic that left my levels completely out of whack. From day one, Jason had his hands full fixing the mess I walked in with—but he handled it like a pro.

We started with bloodwork, and he’s been consistently working to get everything dialed in. I’m feeling better than I have in years. He’s proactive, follows up without being asked, and makes sure the plan I’m on actually works for me.

10/10 — highly recommend

This is by far the best place to go in town, especially for IV therapy! Kelly who I believe manages that side is absolutely incredible! So knowledgeable and always willing to go above and beyond for any needs that I have, my friends, and are employees.. I would highly recommend this location!

Everybody who has been here speaks highly of the experience and interaction with Jason. They NEVER lied!!. I went by for an in-body scan for my fitness goals this year and I had a wonderful experience. Jason was friendly and very thoughtful. He also showed me around to see the services they offer in hormone optimization, athletic recovery, and peptide therapy. I'm excited to go back and try the infrared sauna and red light therapy especially. Highly recommend paying them and Jason a visit.

From start to finish, every visit has been a fantastic experience. The staff is always welcoming and extremely knowledgeable -also just cool.

The InBody scanner is a game-changer for tracking my fitness progress. It is interesting getting clear insights into my body composition that help me stay on track with my goals.

The infrared sauna is incredible! It’s the perfect way to relax and detox after a workout. I leave feeling rejuvenated every time. The cold plunge is another highlight - the benefits for recovery and mental clarity are undeniable. It’s been noticeable in my post-workout recovery.

Finally, the red light therapy is like the icing on the cake. It felt like I was waking up from a nap when the lights shut off. Anyone who hasn’t tried it could go just for this.

Optimize U is truly a one-stop shop for health, recovery, and performance. I highly recommend it to anyone looking to take their wellness to the next level. Thank you for providing a top-notch experience!

We had such a great experience at Optimize U! We did the InBody scanner, sauna, and cold plunge! Jason was super helpful and knowledgeable. Everything was very clean, they had towels and offered water bottles!

Visited for the first time today. Beautiful space and conveniently located! Loved the body scan machine, infrared sauna, and cold plunge. Excited to try out their other services! Jason was incredibly friendly and knowledgeable, and he went the extra mile to make sure we had everything we needed. He was able to answer all of our questions and explain high level medical information in easily digestible ways. This is a great space for athletes and people really looking to improve their health and well being. I am looking forward to going back again!
