About Us/Faculty

PracticalCME’s Mission Since 2008

All of our courses are written to be entertaining as well as informative. We know that a person only retains 10-20% of what is heard for the very first time in a lecture session. That is why we back up our training courses with a variety of supplemental materials to enhance learning and retention…


Our instructors always give out their email addresses and promptly answer any questions and clarifications after the course is over. This is why over 35% of our attendees have already taken one PracticalCME course at any time in the past. Our track record makes us so confident that you will earn back at least double what you paid for the course. That is why all of our live courses are covered by our “Learn It and Earn It” money back guarantee. See the Terms and Conditions when placing your order for details.

PracticalCME’s courses are not for everyone. We cater to the brightest, most-motivated and entrepreneurial providers. Our courses contain all of the basic information and protocols but include the in-depth information that will take you from a provider to a master of the procedure. We want our graduates to perform above the standards of care in their community from the first day that they launch their new service. Some of our topics like Cosmetic Uses for PRP, PDO Thread Lift, and Neurotransmitter/GI are the only online CME courses of their kind anywhere and require a special and highly-motivated aesthetics or wellness provider who wants to stand out among the competition.

Gregory P. Zengo, MD

Medical Director, PracticalCME Medical Training
Director, Atlanta and Phoenix Training
Director of Hotel-Based and Online Training

Gregory P. Zengo, MD has trained hundreds of physicians in aesthetic procedures like Botox, Dermal Fillers, Liposuction, and Sclerotherapy, in addition to wellness services like BHRT with Saliva Testing, and medical weight loss since early 2006. He has forged a unique blend of rigorous evidence-based instruction with practical tips, tricks, and hands-on techniques to help the new practitioner become experienced in the shortest time. His own practice in Georgia serves as a laboratory for everything that is new in aesthetic medicine. What works in reality becomes PracticalCME’s next training course. By remaining in close contact with hundreds of doctors, he is always enriching the course content to make our training the most valuable anywhere. Dr. Zengo is a board-certified OB/GYN specialist. Following his medical school at Emory University in Atlanta, he completed his residency training also at Emory. As a resident, he was awarded the title of Chief Administrative Resident and Resident Teacher of the Year. He has spent 9 years as an Assistant Professor or Clinical Instructor on the Emory faculty.

He has trained with some of the world’s best practitioners in Sclerotherapy, Mesotherapy, Liposuction, PDO Threads, Platelet-Rich Plasma, and Bio-Identical Medicine. These skills have been very well-received by his patients and profitable for his practice. “I found that the most profitable procedures that had the highest patient demand were also the ones that required the least amount of expensive equipment.” And so, PracticalCME was founded to teach physicians new skills, not sell them expensive equipment that will be obsolete in 2 years. Since then, his practice has grown from being 10% aesthetic and wellness services in 2002 to 95% aesthetic and wellness services, and he has not taken a night of call or set foot inside a hospital in over 15 years.

His practice and its adroit transition from traditional medicine to a hybrid of medical/alternative/aesthetic services brought physicians from over 40 states to train one-on-one with Dr. Zengo in his Georgia offices over the past decade. Dr. Zengo began giving his own unique CME training courses in late 2006 but did not cave in to the influence of sponsors who tried to control his content. This led to the founding of PracticalCME in 2008. He has lectured hundreds of physicians since then, most of whom have come back to train in multiple topics.

Dr. Zengo is licensed to practice in Georgia, Florida, California, Arizona, Washington, New York, and Illinois.
