My experience with LIFESTANCE-Has been primarily with DR. Hailey Koepp!!! She has completely made my life comeback to have a sense of reality again. By being able to grasp what’s going on around me, and live in the moment with my family and others-helping and aiding in my walk through this “awful darkness” I’d been stuck struggling in for years!! She has been “100% knowledgeable-information wise and even done AVAILABLE ADVANCED TESTING .. Going above and beyond what’s EXPECTED of her... She is fully on top of HER GAME” about every encounter regarding adjusting MEDICATIONS AND SIMPLY JUST BEING A WONDERFUL HUMAN…..By her “LISTENING NOT HEARING WORDS” out of the “patient’s mouth...”She has taken her time to understand my specific concerns about this and that medication and we have found the best that works best for me!!!!! -Not only has THE COMBINATION ON DR.KOEPP N LIFESTANCE and the MEDICINE AND ALLLLLLLLL THE CONVERSATIONS but MAINLY now …….. I can say I too am apart of the equation …….”I am helping and aiding in making ME A BETTER ME TOO!!!!!!! And for that I want to say Thank you TEAM!!!!!!! YOU’RE #1!!!! I wouldn’t have made it this far with out u DR. KOEPP!!!!

Ask for Haley! She truly, truly cares AND respect her patients. Always on time for appointments and WILL RETURN PHONE CALLS! This woman doesn’t treat you like a medical specimen…but as a human being just as she is. She displays empathy & sympathy. Is up front, open and honest. “SHE LISTENS TO YOU…does not over talk you or shy you down.” *Like so many others do.* You’re not rushed during appointments …and if you’re running into another patient’s time slot…tell her you need more time and she will get you called back for a follow-up ASAP. You are not just a Number or a paycheck to Haley. You’re her priority. Your health, safety & happiness is #1 with her. If you know, you know. #AskForHaley

I had my initial consultation with Haley yesterday. Due to weather issues it was changed to Telehealth. I was reluctant that I would like it, but it is as good as being there. Haley obviously actually reviewed my paperwork before the consultation. Most in the medical field, at all levels, do not appear to even review the information before the visit. She was very easy to talk to, compassionate, and clearly listened to my issues and concerns. She discussed an action plan in detail, and asked my thoughts on it. Sounded like she made a great plan. I highly recommend her, and for those that are reluctant to try Telehealth, give it a try with her.

I started seeing Haley Koepp and Physc care consults in Missouri after graduation from center point from getting clean from pain pills. I have never met such caring, supportive, attentive, and doesn’t rush you through. She deserves more than 5 stars! She made me believe that there are still individuals in the medical field that truly and honestly care. Haley if you see this..thank you again! I’m 4 years later I’m still sober and couldn’t have done it without your support and you caring and checking on me! Taylor Shipp Johnson

I see 3 different doctors at lifestance Chesterfield. Each one of them listen to me and don't just wait for their turn to talk. Thanks to the amazing and compassionate psychiatrist, therapist, and EMDR therapy i have been able to take my life where I want it to go at my own will. 10/10 do recommend lifestance. I love that you can see and read about the dr you pick according to your needs. Lifestance helped me when I was at my lowest. They build you up and treat you like a human not a condition.

I had a telehealth visit with Haley Koepp because of bad weather. It was new to me but it was ok. She’s very kind, good listener and attentive to what you’re saying. Shows concern and offers her input. While I enjoyed my telehealth visit, it needs some tweaking. I’ve found a caring doctor who takes time with you and I’m thankful I’ve found her and Life stance.
