Founder, Medical Director

Dr. Gustav Lo, MD

During his 30 year career as a primary care physician, Dr. Lo first applied regenerative medical techniques such as PRP injections to orthopedic cases in the early 2000’s; following those successes, he then brought similar techniques to our aesthetic practice. Our results mirrored the research findings in other centers – regenerative techniques can reverse some degenerative conditions and “youthify” our tissues and physiology. With that, he founded RegenCen (a separate division of CSLC) in two northern Michigan locations as a treatment center focused on helping you age better. RegenCen merges the most proven regenerative therapies with bioidentical hormone programs for men and women, tackling some of the biggest impediments to living well over 50. Dr. Lo earned his undergraduate degree from the University of Michigan and his MD from Michigan State University. He founded Northern Michigan MedCenter primary care and urgent care centers, operating them for 30 years with over 1 million total patient visits. Since 2009, Dr. Lo offered treatments at CSLC in liposuction and laser surgery. He has performed over 4000 liposuction procedures in Petoskey and Traverse City and thousands of Laser Lift treatments for aging. The remainder of his professional time as a physician is at RegenCen. He continues to see patients and offering regenerative therapies and remedies for erectile dysfunction, orthopedic conditions, arthritis and male testosterone replacement, was well as supervising our physician associates who specialize in women’s care. As regenerative medicine continues to advance, Dr. Lo and his team are dedicated to the “youthification” of our clients, bringing exciting, scientifically proven treatments to patients in Traverse City and Petoskey who want to look, feel, and live better at every stage of life.

Kolleen Werly, PA-C

Kolleen knew she’d found her career calling here when she met an advancing, experienced group of medical and aesthetic clinicians who offer clinical treatments to help people live better, look better and feel better. “I walked in to my dream job,” she says.

As CSLC and RegenCen’s Medical Lead and a Physician Associate in Traverse City, she thrives on educating patients on new techniques, products and procedures that help them reach their goals.

Kolleen offers hormonal consultations, bioidentical hormone replacement with pellets, and PRF / PRP injections for both  orthopedic conditions and hair loss. And she also specializes in feminine rejuvenation treatments for vaginal dryness and bladder control.

“The most satisfying part of working with patients is seeing how minor changes in a person’s appearance can have such a measurable impact on their happiness and self-esteem,” she says. “And RegenCen improves daily life in a very similar way. When women eliminate stress incontinence and elevate life in the bedroom – those are game changers.”
