Jennifer Smith, RD, LD, CDCES

Director of Lifestyle and Nutrition

Jennifer has also lived with type 1 diabetes since she was a child, so she has first-hand knowledge of the day-to-day events that affect diabetes management. She attended a diabetes-specific sports training camp in 2008 where she discovered her passion for achieving fitness goals while living healthfully with diabetes. In 2009 she successfully completed her first triathlon. This brought a deeper understanding of athletic training requirements and the importance of nutrition to realize athletic goals.

Jennifer holds a Bachelor’s Degree in Human Nutrition and Biology from the University of Wisconsin. She is a Registered (and Licensed) Dietitian, Certified Diabetes Educator, and Certified Trainer on most makes/models of insulin pumps and continuous glucose monitoring systems. She is an active member of the American Diabetes Association, American Association of Diabetes Educators and Team WILD (We Inspire Life with Diabetes). She is also a contributing author for the Diabetes Sisters website. As a talented dietitian, diabetes educator, athlete and person with diabetes, Jennifer is in a unique position to assist Integrated Diabetes Services’ intensively managed clients.

Jennifer and her husband Nathan, an Ironman athlete in his own right, share their home with their sons Oskar and Conan, their dog Fillmore and cat Cornelius. In her free time, Jennifer enjoys running, cycling, swimming, yoga, and kayaking. She also loves hiking with Nathan, Oskar and Fillmore. A culinary “experimenter”, she is fond of cooking and baking, with an eye on vegetarian options. Tops on her annual “to-do” list is to travel to strange and exotic places outside the US.

Alicia Downs RN, MSN, CDCES,  BC-ADM

Director of Patient Care and Education

Alicia’s diverse nursing career has given her experience with a broad range of clients and a variety of health conditions in addition to diabetes. One of her 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 a proud graduate of the Cecil College School of Nursing and received her Bachelor’s and Master’s of Science in Nursing from Western Governors University. She is an active member of the American Association of Diabetes Educators and Maryland Nurses Association.

Alicia manages her diabetes with an insulin pump and continuous glucose monitor. Her 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 her own health care and educate those around her.

“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.”

After years as a director of a childcare center, Alicia made the career leap into nursing with the goal of becoming a diabetes educator. Her 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 her clinical practice.

Alicia’s talents and passions are not restricted to diabetes education. She can be found as a regular performer on stage/film projects and with local bands.  As an award winning steampunk and cos-play designer, she enjoys building costumes and fashion pieces for her husband Tim and son Asher. Alicia and Tim also share black belt martial arts training (Alicia holds a first-, and Tim a third-degree black belt in Tang Soo Do). In more sedate moments, Alicia can be found curled up with a cup of tea, good book and her dogs Billie and Wicket.

She earned a bachelor’s Degree in Human Nutrition from the University of Northern Colorado in Greeley and completed her internship at Baylor Medical Center in Dallas.  She then relocated to Kona, Hawaii where she built a successful private practice as a Certified Diabetes Care & Education Specialist.
