Dr. Kimberly Lemke

Licensed Clinical Psychologist • Sleep Science Coach • Author • Founder/CEO, Drift® Sleep & Wellness Institute

Dr. Kimberly Ann Lemke is an esteemed licensed clinical psychologist, award-winning entrepreneur, and nationally recognized expert on the science of sleep. With over two decades of experience, she has helped thousands of individuals reclaim their energy, quiet their racing minds at night, and finally put an end to those frustrating 3 AM wakeups.

A 2020 recipient of the prestigious Enterprising Women of the Year Award, Dr. Lemke brings a rare blend of clinical expertise, leadership, and real-world relatability to her work. She’s also a past chair of psychological associations and various mental health boards, where she played an active role in shaping the future of mental health care and wellness initiatives.

Dr. Lemke utilizes Cognitive Behavioral Therapy for Insomnia (CBT-I) and is also a Sleep Science Coach. She’s the creator of the Drift® Method, a groundbreaking online sleep course designed to go far beyond the usual "just sleep more" advice. Her unique approach is built around the idea that “Sleep is a DAYTIME Issue!™”—meaning what you do during the day directly influences how well you sleep at night.

Through practical strategies, relatable analogies (like her well-known Sleep Balloon concept), and real behavioral science, The Drift® Method teaches how to optimize your workplace and daily habits to improve focus, energy, and resilience—without sacrificing performance.

Dr. Lemke is a sought after keynote speaker and her work has been featured in corporate wellness programs worldwide, national conferences, legal and healthcare organizations, and the bedding industry—where she helps brands and businesses translate sleep science into real value for their teams and customers.

She also leads virtual and in-person workshops on sleep, burnout, stress, and holistic well-being, bringing her trademark energy, empathy, and humor to every talk.

In addition to her clinical and coaching work, Dr. Lemke is a published author, passionate speaker, and advocate for mental health awareness and sleep equity.

As the Founder and CEO of the Drift® Sleep & Wellness Institute, her mission is simple but powerful. Guided by Desmond Tutu’s words, “There comes a point where we need to stop just pulling people out of the river. We need to go upstream and find out why they're falling in,” she views sleep not just as a symptom to treat, but as the starting point for lasting change—preventing the fatigue, anxiety, and burnout that so often follow.
