Owner / Medical Director

Dr. Phil Hong Nguyen, MD has the honor of being a national speaker for Allergan, the manufacturer of Botox, Juvederm, Kybella, and Coolsculpt. Physicians and clinicians across the country come to Happy Clinic Denver to train under Dr. Phil on the latest aesthetic techniques. He also is the education director for the American MedAesthetic Association. Dr. Phil has been a licensed physician in the state of Colorado for the past 20 years.  He also holds licenses in the states of Indiana and California. He graduated from Indiana University School of Medicine in 1998.  He has been doing cosmetic/ aesthetic procedures since 2001.  Dr. Nguyen prides himself in being an artist and minored in Fine Arts Studio for his undergraduate studies.  He paints, draws and sculpts. Thus, he naturally gravitated to the cosmetic/ aesthetic field of medicine. Dr. Nguyen trained in family practice and did his internship at the University of Colorado Swedish Medical Center.  


Dr. Phil takes great pride in giving his patients a natural looking appearance, and has had over 16 years experience performing injectable procedures. He personally sees about 1000 faithful patients a month, making him one of the most experienced and sought after cosmetic physicians in the country. "We are all just a few millimeters away from looking like Angelina Jolie or Brad Pitt," and "Anyone can stick a needle into you, but it takes an artist to make it look good!" are two of his favorite quotes.


Dr. Phil speaks English and Vietnamese fluently, and knows enough of Spanish, French, Thai and Mandarin to be dangerous. He is a world traveler and foodie, with his favorite place to visit being Southeast Asia. Dr. Phil is a member of the American Academy of Cosmetic Surgery.

Outside of the clinic, Dr. Sharma enjoys being outdoors and exercising just as much as he enjoys being indoors with music or a good book. He is always looking for suggestions on where next to hike or to eat!

Alfonso’s joy for life comes from his appreciation of family close friendships, movies, dancing, music, travel, and good food.

Clayton knew he was more fabulous than the other boys his age, in the metro of Huntsville, Alabama, from very early on. Before he even knew the word “aesthetics”, he was fascinated by high fashion, couture, the arts, make-up, acting, and modeling, and all things visually appealing and alluring. When an opportunity came to move to the big city (Los Angeles, CA) in 2012 - he said, yes, uprooted his life, and pursued a new start in the West Coast in a city he only dreamed of ever seeing, let alone living in. There, his people skills, business skills, and compassion for others took him on a wild journey of multiple industries: from retail and non profit work, to cosmetics and dentistry.

In 2017, it was time to settle and lay roots in a city and state that would become home for the unforeseeable future. This transition brought Clayton to the Happy Clinic and Dr. Phil Nguyen, who helped shape and mentor his future into becoming a licensed Aesthetician, passionate about helping people feel confident in the skin they live in. Clayton was able to become a Certified Laser Specialist, and graduated from the Rocky Mountain Laser College with the generous support of Dr. Nguyen.

Clayton specializes in acne, hyperpigmentation, skin rejuvenation, and patient education at The Happy Clinic, and loves taking patients from the start of their aesthetic journey and mentoring them to success and fulfillment of their skincare goals. When Clayton is not at work he is most likely doing karaoke, climbing a mountain, or cleaning something up. His beauty philosophy is if it bothers you in the mirror, stare it down and bother it back! His life philosophy is that everything happens for a reason, and that the only control we ever have, is over ourselves.
