alicia downs

Alicia Downs RN, MSN, CDCES,  BC-ADM

Director of Patient Care and Education

Alicia’s diverse nursing career has given them experience with a broad range of clients and a variety of health conditions in addition to diabetes. One of their passions is advocating for the needs of her patients, whether it be in overcoming insurance restrictions, obtaining community resources, or coordinating with school systems and medical providers. Alicia is an active member of the Association of Diabetes Care and Education Specialists.

Alicia manages their diabetes with an insulin pump and continuous glucose monitor. Their rocky road included years of mis-diagnoses and ineffective treatments during her college years. That experience gave Alicia the incentive to take the lead in their own health care and educate those around them.

“In this day and age, everyone with diabetes deserves state-of- the-art care, treatment and education,” professes Alicia. “Nobody should have to go through what I went through early on.”

Alicia’s life has included many unique medical challenges including multiple auto-immune diagnoses and orthopedic conditions. However, Alicia chooses to view these as opportunities to grow stronger rather than as barriers, and applies this approach to their clinical practice.

Areas of clinical specialty for Alicia include working with patients through cancer treatment, Type 3C diabetes, Diabetes management along with complex medical challenges, diabetes management in combination with behavioral and mental health challenges, as well as Tandem diabetes device optimization. Alicia is also a proud member of the LGBTQIA+ community and is honored to offer knowledgeable and sensitive care to her communities.

Alicia’s talents and passions are not restricted to diabetes education. They can be found as a regular performer on stage/film projects and with local bands.  As an award winning steampunk and cos-play designer, they enjoy building costumes and fashion pieces for themselves and their son Asher. Alicia is an avid practitioner of both eastern and western martial arts.  In more sedate moments, Alicia can be found curled up with a cup of tea, good book and their dog Wicket.
