REGISTERED NURSE

John McCollum

John is a registered aesthetic nurse specialist with the experience and eye for detail to provide you with superior results. Prior to John’s time as a registered nurse, he developed his skills working for luxury brands in client services and retail business development. This experience adds to his special skills in communication and patient care. John entered the field of medical aesthetics as a surgical coordinator for leading New York plastic surgeon Dr. David P. Rapaport, MD. Here, he developed his passion for patient care and education, inspiring him to pursue his education as a registered nurse. John also holds a Bachelor of Science in Nursing, a Bachelor of Arts in International Affairs, and a Bachelor of Arts degree in French.

Upon achieving licensure as a nurse, John approached Dr. Rapaport to pursue an intensive hands-on training program in cosmetic injectables and non-invasive rejuvenation treatments. John’s experience in medical aesthetics now spans nearly a decade, including both administrative and clinical responsibilities. He combines his background in luxury service with his focused nursing experience in plastic surgery to make him a uniquely capable medical provider. John is currently completing his Master of Science in Nursing to become a nurse practitioner specializing in primary adult care.

Client Testimonials

Run, don't walk! There are injectors and then there is John. He is talented, confident, and makes you feel like you are in great hands. Which you are. He not only has a creative eye for proper natural placement but also rarely, if ever, makes you bruise. Simply put, he cares. I cannot speak more highly of his practice, touch, or bedside manner. I will always seek John for any and all facial aesthetic work. Thank you!

I had the best experience with John. He made me feel extremely comfortable and my lips turned out so natural. I will definitely be back - so happy to have found someone I trust. 10/10 recommend.

Bridget G.

Had a appointment with John McCollum: 3 days after the treatment I can say this is definitely the best Dysport injection I had in 15 years - he is the first professional who managed to achieve the results I wanted on my very strong 11 muscles! Best of the best in the city in my opinion, professional, detailed and with integrity, John really shined for his knowledgeable approach.

Aethos is the place to go if you want to look beautiful. John McCollum, RN is extremely talented and super kind. I have been working with him for over a year and his skills with lip filler and botox are incredible. I am SO happy with the results. I trust him and him only. I highly recommend working with him if you want great results with minimum downtime. John took an impressive amount of time to discuss the procedure with me. He explained the types of fillers available, what he recommended for my specific facial concerns, and what I could realistically expect in terms of results. His thorough explanation helped me feel informed and confident in the choices I was making. LOVE Aethos!
