Born and raised in Denver, Colorado, Dr. Seaman completed her residency in Emergency Medicine at the Denver Health Medical Center, graduating in 1999. She went on to join Ergentus, a well-respected Emergency Medicine physician group, and has been a full partner there since 2002. She currently works as an Emergency Physician at Exempla Lutheran and Exempla Good Samaritan Medical Centers. She has over 14 years experience with nerve blocks and complex wound repairs, in addition to many other procedural skills. 

Dr. Seaman started indulging her more artistic side at the age of 40, enrolling in oil painting classes. This eventually led to an interest in the field of facial aesthetics. In 2012 she received specialty training and certification in the field of facial dermal filler and Botox® Cosmetic injections. She followed this up with advanced dermal filler training, becoming a skilled injector including the use of microcannula techniques. She has also received additional facial rejuvenation training under the guidance of Dr. Ruggero with specific focus on ArqueDerma® lifting techniques. 

Dr. Seaman is passionate about the science of facial aesthetics. She understands that small and specific changes to the face can make huge differences in attractiveness, poise, and hopefully the way clients feel as a result. Dr. Seaman’s philosophy is a simple one – listen intensely, understand every cosmetic detail, and deliver safe and expert results using the best techniques available.

Shelley has 10 years experience in medical aesthetics and obtained advanced training with IPL treatment and protocols, microdermabrasion, micro-needling, chemical peels and radio frequency devices. She spent many years in the technology industry and has a master’s degree from Regis University. When she moved to Colorado in 1986, she fell in love with the active lifestyle. However, she realized that spending time outdoors with sun, wind, altitude and lack of humidity was tough on the skin and caused premature aging. This was her inspiration to start a career in aesthetics and to learn about and utilize new technological advances to combat these elements and help clients maintain great skin while enjoying outdoor activities.

Shelley spends as much time as possible outdoors biking, hiking and skiing. She is a PSIA Certified Ski instructor and shares her passion for the outdoors with her two sons and 3 grandchildren.
