Meet the medical experts who are here to guide you on your path to optimal health.

Paul Weinberger, DO



“I am a board certified emergency medicine doctor. I love traveling, shopping, food, working out, and believe in hormone therapy as the foundation to optimizing my quality of life.”

Jessica Matis, DNP/ACNP-AG



“My husband and I have both been tossed around the mainstream healthcare system. Walking into appointments with symptoms and being told our labs “were normal”, but feeling the opposite. We have brought this company to Louisville to help others who have been in the same situation. We believe both men and women should be treated by symptoms while using lab work as evidence to the treatment plan, not dictate the treatment plan.”

Rachel Killen, MSN, APRN



I have 13 years of experience in the medical field and a Masters Degree in Family Practice from Spalding University. I am very passionate about health and educated in hormone therapy, aesthetics & functional medicine so that I can help my patients look and feel their very best. I don’t believe in a one-size-fits-all treatment plan so all of my patients are treated individually based on their symptoms & supporting lab work. My hope is that my patients leave here feeling not only educated but empowered by their health care plan and eventually optimized!

Dylan Martin, RN



“I’ve been on the receiving end of being told my labs were “normal” in and out of the VA. At an age most would consider young I had all the signs and symptoms of low testosterone. While there were places that would help me, they were also very expensive. At the end of nursing school I was offered the opportunity to help others in a similar situation, but at a much more affordable rate with the same attention to detail in regards to planning proper care.”

I have been so impressed with this clinic and their knowledge about how to optimize my weight loss journey. Rachel is awesome and so relatable! She’s a hype girl for sure ! They seem to a wonderful staff who really cares about the health of their patients!

Terra Renee Arla Customer

I am so impressed with Rachel's knowledge and professionalism. She thoroughly discussed my treatment and ensured my comfort throughout the duration of my visit. I am about 1 month into my Sculpt series, and I am already seeing drastic results on my once stubborn abdominal area. I also want to mention that the entire staff is so friendly and always makes me feel right at home. OptimizeU is truly a one stop shop filled with knowledgable professionals eager to help you reach your goals!

Mary Meyer Customer

I’ve been to Rachel several times for microneedling and Botox. She takes great care of me. She guides me to pick the treatments that will best meet my skin care goals. She takes a lot of time to make me feel comfortable. She’s very diligent about properly numbing me before the treatments that require it. She also keeps an open line of communication after treatments and can easily be reached if I have any follow-up questions or concerns. I cannot recommend her services enough. The treatment rooms are very clean, and the design is awesome. I tell everyone that I know that they need to go see her for any of their hormone or skin concerns.

Rachel Ray Customer

Love this business and my experience with them! The staff is so helpful to direct you to all options to achieve your goals. Dr Jessica is very knowledgeable about hormones and can help you better understand your lab panel. I’m so thankful I found them!

John Miller Customer

So thankful I found Optimize U! The service is far better than any place I have ever been and they are very well educated on any question you may have. Friendly staff and a great environment. Love the fact that I have stepped outside my comfort zone and given Cryotherapy a try. Totally worth it! It’s TWO THUMBS UP from me!
