My area of specialty lies in the practice of nursing in rural areas. I have worked in arctic Alaska, critical access hospitals, and home health/hospice in remote areas. As healthcare delivery changes, and the role of nursing shifts away from acute care and into chronic disease management and health promotion, rural nurses will be invaluable links to provide quality care. 

My teaching experiences begin in rural Alaska with some of the first distance delivery methods in place. It was quite interesting to teach American Heart Association CPR to Inupiat Eskimo first responders who truly understood how far away you might be from an acute care hospital setting. Currently I teach Professional Nursing courses for the undergraduate nursing program helping students see the complex relationships between healthcare policy, cost of care delivery, and the unique role of each staff nurse as a leader.   All nurses are leaders. My most recent passion has been to develop Interprofessional healthcare teaching teams to allow students to leave their silo style education and develop collaborative care plans.

As a leader within the Traditional Track in the Undergraduate Nursing Program I seek to inspire our faculty team to find the best way to educate the nurses of the future, teaching students to blend skills in technology with compassionate, holistic, quality care.  We seek to create nurses who are strong patient advocates, nurses who use the Benedictine values as part of their anchor for moral decision making, and finally nurses who are able to seek answers rooted in Evidence Based Practice.  As healthcare becomes increasingly complex, the nurses of the future are called to imagine new delivery care models.  Imagination and problem solving can be stimulated by accessing a liberal arts foundation. 

My outside interests include experimentation in a broad range of textile arts, extensive travel abroad, and the production and cooking of local foods.

Upon graduating from St. Scholastica with a baccalaureate degree I found myself launched into a variety of wonderful practice experiences.  My early nursing career was focused primarily in the care of the obstetrical and newborn client, as well as with the acutely ill hospitalized adult client, particularly those with cancer.  But the pull back to St. Scholastica and to education in particular became very strong in time, and I decided to pursue a graduate degree as a Clinical Nurse Specialist in Adult Nursing.  This preparation afforded me the incredible opportunity to begin a career that focused on the education of nursing students.  As a faculty-member in the Traditional Undergraduate Program, School of Nursing, I am privileged to work with students in a variety of venues; classroom, skills lab, simulation lab and the clinical environment. 

My philosophy of teaching is to serve as an “experience facilitator” for the students I work with.  Learning experiences occur in the most unexpected and unpredictable ways if one is receptive and curious.  I have quickly come to realize that health care changes much too fast to prepare students for all that they are likely to encounter.  If, however, I can teach students to be an effective lifelong learner, I have succeeded in teaching.

Kristy Gunderson is an Assistant Professor in the traditional undergraduate nursing program, joining the team in 2018.  She holds a M.S. in Health Education and Promotion from Walden University and a Bachelors of Science in nursing from the College of St. Scholastica.

Kristy’s nursing interests includes mental health with experience providing care across multiple settings and populations, community health nursing, working as a licensed school nurse with children birth to 12th grade, as well as forensic nursing with experience working as a sexual assault nurse examiner. 

Kristy’s desire to pursue teaching at Scholastica was prompted by the positive interactions she working directly with Scholastica nursing students as a community clinical and capstone preceptor in the school setting. 

In her free time, Kristy enjoys spending time with husband and three children, watching them participate in their various activities and traveling to new places.

I graduated from CSS in 2013 with my BSN and started working as an RN shortly thereafter. After six years of general and trauma critical care bedside nursing at a Level One Trauma Center, I decided to make a change and teach full time while I pursue my DNP from CSS. 

I truly enjoy working with my students and helping them understand what it means to be nurse. I feel my past experiences in critical care medicine help me relate complex concepts in a way that is understandable and applicable to practice. I always do my best to make sure that all my students learn as much as they can so that they can become the best nurse they can be. 

I appreciate the emphasis that St. Scholastica places on holistic nursing. It should always be our goal as health care professionals to provide the best possible care to the whole patient, and not just the physical being.
