Jennifer is the best, don’t think, just go Energize yourself!
Jenn and her staff are the best. No one is just a number at Energize. Jenn and her staff actually care about your goals and over all health. I’ve been to 2 previous clinics, Man up in O’Fallon and Summit in Cottleville. The customer service and overall care given by Jenn and her staff at Energize is by far the best care I’ve received. My primary care doctor, neurologist, and cardiologist all agree agree with the care Jenn and Energize provide. You want good care, Energize is the place to go!
Jenn and her team are the best! I would totally recommend them to anyone. Jenn is so thorough and she cares about her clients. I just love her
Customer service is so important to Energizer’s clients🩷

LOVE THAT SHE ADVOCATES FOR HER PATIENCE!
Nobody better in the business family atmosphere. Do your body a favor and go see Jennifer and her staff today.
Best in the business!!!!!
I've gone to Jenn for almost ten years now, and there's a reason for that. I have an absolute trust in her knowledge, her intelligence, and a deep respect for her staying up-to-date in all her specialties. What's more, she *actually helped me* with my symptoms after being dismissed again & again by other MDs. Being female, 40s, & feeling amazing is 100% possible! Forever grateful!
Great place. To feel better quick
