About Doctor Allen

Dr. Shannon Allen is an Otolaryngologist with a passion for aesthetics, blending medical precision with artistic flair. She graduated with honors from the University of Michigan in 2002 before attending medical school at Wayne State University in Detroit, where her fascination with the human body as a beautiful machine began. After completing her surgical residency at Temple University in Philadelphia, Dr. Allen focused on head and neck surgery, practicing at MaineGeneral from 2013 until 2020, when she transitioned into the field of aesthetics.


Dr. Allen offers a unique approach to patient care, combining cutting-edge techniques like CO2 laser resurfacing with a deep commitment to natural, long-lasting results. Certified in a range of aesthetic treatments—from neuromodulators to scar camouflage—she tailors each plan to the patient’s individual goals, helping them look like the best version of themselves. With over 10 years of experience studying the efficacy and safety of fillers, Dr. Allen applies her knowledge to ensure that every treatment is both effective and safe. Her background as a medical illustrator has also given her a refined eye for detail, which she applies in her work to create subtle, natural improvements, always staying true to her oath to deliver treatments that provide real results, leaving her patients feeling confident and rejuvenated.


When she's not working, Dr. Allen is busy chasing after her 2-year-old, bringing the same care and sense of humor into motherhood that she applies to her practice. In her downtime, she enjoys painting in oils, a practice that naturally complements her aesthetic work by requiring the same patience and attention to detail, where thoughtful, gradual changes lead to balanced, lasting results.
