Stacy Vencill, PA-C, MPH

Physician Assistant

Tenure at Company: 11 years
Favorite Treatment: Botox Cosmetic.  Between the ability of Botox to prevent and correct lines or areas of the face that we feel are undesirable – matched with it’s decades of safety research, make it the most cost-effective treatment a patient can do.
Favorite Product: SkinMedica TNS Recovery Complex.  We know as we age our skin needs multiple forms of stimulation to keep up with the anti-aging process.  Growth Factors are just one of them, but in my opinion one of the most impressive.

Stacy is a graduate from the George Washington University Physician Assistant Program, in Washington DC. At GWU, she completed a Masters of Science and a Masters of Public Health, specializing in Maternal and Child Health. After graduation from PA school, Stacy realized that she could not pick just one specialty in medicine, so she worked in both Family Medicine and Aesthetics/Anti-Aging.

After working for 6 years in multiple medical spas and plastic surgeon offices, Stacy refined her injection skills, techniques and discovered she really enjoyed the art of aesthetics and getting to know her patients, ensuring that they’re always completely satisfied with their treatments. Unfortunately, she realized that her priority and focus on patient care was not shared with her previous employers.

In 2009, she decided to start her own practice and she founded Concierge Aesthetics. She partnered with a colleague – Dr. Neil Neimark, a Concierge Family Medicine doctor who shared the same passion for customer service and patient care.

In 2017, Stacy opened her own office in Irvine and expanded her treatment offerings to also include Medical Aestheticians and Laser Treatments. Although Stacy has experience with a vast number of laser procedures, she has developed a passion for injectables over the last few years which has driven her to complete advanced training in BOTOX and dermal fillers (such as Bellafill, JUVÉDERM and Voluma XC). She particularly enjoys doing BOTOX and fillers because of the “artistic ability that is required to augment the face with natural and subtle accents.” In addition, she is a National trainer for Allergen, Bellafill and Suneva, assisting and teaching other practitioners in the administration of BOTOX and multiple dermal fillers.

Susie Ergun

Susie Ergun, PA

Physician Assistant

Tenure at Company: 3 years
Favorite Treatment: Laser Genesis. Whenever I feel my skin is starting to look dull, I like to do a Genesis treatment to brighten the skin and tighten my pores. I prefer to get a Hydrafacial before it for optimal pore tightening. This combo makes my skin feel very soft and look radiant. I try to do this at least every 2-3 months consistently.    
Favorite Product: TNS Essential Serum. This duo product makes such a difference in my skin. It makes it feel silky and luxurious. It’s a perfect part of my nighttime skincare routine.

Susie Ergun attained her Master of Science in Physician Assistant Studies from Western University of Health Sciences and gained board certification/licensure in California in 2005. She is also an alumnus of the University of California, Irvine with a Bachelor of Science degree in Biological Sciences. Her career as a Physician Assistant started as a first assist within the field of Oculoplastic Surgery and very quickly, she became interested in laser technology and its application in Aesthetic Medicine. She was on the front lines inutilizing advancing technology, such as Fraxel laser, just as laser procedures were becoming increasingly popular in Orange County.

Always keeping her hand in the Aesthetic field of medicine, she went on to expand her career into the field of Gastroenterology for 7 years, as well. She enjoyed the balance of helping those who were ill with stomach and intestinal disorders feel better internally, as well as helping her patients seeking aesthetic enhancements feel better on the surface. Susie went on an international excursion for 2 years in Istanbul where she managed a boutique hospital accommodating an influx of international patients seeking care for aesthetic and medical treatments, including hair transplantation, injectables, laser treatments and PRP/mesotherapy treatments.

Susie has developed a passion for health, wellness and beauty and with her vast experience in the field of Aesthetic & Laser Medicine, she decided to fully dedicate her practice to making her clients look and
feel like the best version of themselves. She has developed a strong bond with her portfolio of patients and enjoys the prospect of new patients becoming part of “the family”. She has gained a loyal following of patients who continue to seek care with the most innovative technology and products available. She is mostly known for her ability to comfort patients and be a motivational source for patients who strive to achieve their aesthetic goals.

Tanya Robertson

Bombshell Beauty + Skin Care

Tenure at Company: 2 years
Favorite Treatment: SkinPen – Microneedling. This minimally-invasive powerhouse skin rejuvenation does it all- increases collagen and elastin production, treats deep acne scars and helps pores appear much smaller. To top of off microneedling allows skincare products to penetrate better and work more effectively and there is very little downtime. The look and feel of your skin significantly improves even after one treatment.    
Favorite Product: SkinMedica AHA/BHA. I love this gentle exfoliating wash because it removes dirt and makeup easily and always leaves my skin looking clean and radiant.

Tanya comes to us with almost a decade of experience at a high-end spa in Newport Beach. She’s an expert at results-driven, custom oxygen facial treatments using cutting edge technology and high-end skincare. She is also highly skilled at waxing and brow shaping.

“It is my mission to help bring out the confidence that sometimes fades when life forces us to make ourselves last on the priority list. It is with gratitude and honor to be chosen for your beauty needs. I do not take that role lightly and I genuinely feel this craft is the pulse to my beating heart. The respect and passion I have for this industry is something I deeply cherish and it is my hopes that you feel that passion after one of my services.”

Tenure at Company: 8 years
Favorite Treatment: Laser Genesis. It makes my skin brighter and there’s no downtime and I can just feel a difference in my face and makeup. Great for going out before a party or event.    
Favorite Product: SkinMedica HA5. Although I’m very dry and break out if I use certain moisturizers – HA5 doesn’t do that. It moisturizes and smoothes my skin I just love this product

Tina Porter

Aesthetics Coordinator

Tenure at Company: 5 years
Favorite Treatment: Botox Cosmetic. Botox is amazing. It helps alleviate my TMJ pain, reducing my fine lines for a more relaxed natural look and softens my neck bands.
Favorite Product: SkinMedica HA5. I love how HA5 hydrates my skin. I’ve noticed a difference in both my pore size and my overall skin health.
