Shannon Callahan


Shannon has over 12 years of experience as an aesthetician and 14 years as a New Jersey licensed cosmetologist.

After receiving her cosmetology license, her first-hand experience of suffering with acne led her to go back to school to further her education in skin care.

She has also obtained a medical assisting degree which has made her a well-rounded, sanitation-conscious, esthetician.

Shannon specializes in Microdermabrasion, DiamondGlow Facials, Microneedling, Chemical Peels, Dermaplaning and  many different types of Lasers. Her personal history with acne makes her an excellent choice for those suffering with problematic skin.
