Your biology determines the ceiling of high performance. Dr. Susan Lovelle builds the plan that raises it, and tests what most doctors never order. Hormones, metabolism, gut, inflammation, 50+ biomarkers. Then she uses your own numbers to rebuild your energy. Test, don't guess. She's the founder of Balanced Performance, where she works with executives, business owners, and high-performers on energy, weight, and hormones. She also designs the programs and trains the care teams delivering them. She came to this work the hard way. A former professional ballerina, then a Columbia University-trained plastic surgeon with more than two decades in practice. Then three ICU stays for blood clots, the third one leading to sepsis. Her labs looked "fine," and her husband is the reason she's alive. She's the author of Thrive! The Five-Week Guide to Mastering Your Energy at Any Age, a TEDx speaker, and has been featured on The Doctors, Lifetime TV, The Huffington Post, Forbes, Good Morning Washington, and Good Day Charlotte. If your labs are "normal" but you know there's more, you're who she built this for.
