Margaret A. Stark PA-C
'I strive to parallel the quality and standards of care exemplified by Dr. Stockton. We work together to provide honest answers and advanced solutions for our patients.'
Margaret (Maggie) Stark earned her Bachelors of Science degree from Boston College in 1998. She went on to earn a Masters of Medical Science in Physician Assistant studies from Midwestern University in Glendale, Arizona. Stark was certified by the National Commission on Certification of Physician Assistants (NCCPA) in 2001, and then became licensed to practice medicine in the state of Arizona under the supervision of a physician. She has been practicing as a Certified Physician Assistant (PA-C) specializing in dermatology under the tutelage of Toni C. Stockton M.D. F.A.A.D. since 2001.
Stark's Physician Assistant related memberships include: Phoenix Dermatologic Society, Arizona State Association of Physician Assistants (ASAPA) and the American Academy of Physician Assistants (AAPA). Stark has also received training in medical, surgical and cosmetic dermatology. In addition, she is trained in the treatment of acne and sun damage with BLU-U® light with Levulan®, chemical peels, skin growth exams and photo-therapy.
Laura Devlin NP-C
'My sister in law was diagnosed with melanoma in 2006. I spotted the funny mole on her back at the beach and urged her to see a dermatologist. Fortunately, it was detected early enough and was completely removed. That was my 'aha' moment. Dermatologists save lives!'
Laura graduated with a Bachelor's Degree in Nursing in 1986 from the University of Toronto. During the first part of her career she worked as a registered nurse at the University of Michigan hospital where she worked in the inpatient and outpatient settings of the Neurology/Neurosurgery department. Ten years later she moved with her family to Phoenix and decided to pursue a Master's degree in nursing and become a nurse practitioner. It was in graduate school that Devlin's interest in dermatology came about. After graduating from ASU in 2001, she worked with a rheumatologist in Scottsdale, Arizona. Because many of Devlin's patients had skin issues in addition to their joint pain, her desire to practice dermatology increased.
Following her rheumatology work, Devlin was able to transition into a full-time dermatology position in Paradise Valley, Arizona, and after that she transitioned into a position as a Nurse Practitioner at Stockton Dermatology.
Devlin is trained to do skin growth exams, biopsies, treat acne and perform cosmetic procedures using lasers.
Devlin was board certified as an adult nurse practitioner in 2001 by the American Nurses' Credentialing Center. She is licensed through the State of Arizona Board of Nursing as both an advanced practice and registered nurse. She has been a member of the Dermatology Nurses Association since 2006.
Alison Schriefer PA-C
“Skin is like a picture, it says a thousand words. It reacts and changes in response to stress, sun, food, allergens, hormones, weather, etc. I love practicing in a specialty where the diagnosis is right before your eyes!”
Alison Schriefer is an Arizona native. She earned her Bachelor’s degree in Physiological Sciences from the University of Arizona in Tucson, AZ in 2005. She began her training with Dr. Stockton in the summer of 2009 as a student in the Physician Assistant studies program at Midwestern University in Glendale, AZ.

Alison was invited to join Stockton Dermatology in 2011 and she started with the practice in November.
