Christi J Hokel, MS, BSN, RN

Clinical Director of Nursing

Having a strong strong passion for helping those in need and the desire to change peoples lives is what led Christi to become a nurse. She graduated from Grand View University with two Bachelors Degrees.  The first in Health Care Studies and the second in Nursing. She also received a Minor in Psychology.  She later went on to receive a Master's of Science from The Philadelphia College of Osteopathic Medicine.

She began her clinical career working at Mercy Hospital in Des Moines as a Cardiac/Telemetry nurse.  From there she transitioned into the field Emergency Nursing and later into Hospice.

In 2004 Christi launched Signature Healthcare in Des Moines, Iowa.  Today the nursing agency employs over 200 nurses and caregivers and has become Iowa's top provider of medical staffing.  Signature Healthcare places nurses in hospitals, long term care facilities, physician groups, occupational health, mental health, rehabilitation, hospice, school districts and in-home health care.

In 2007 Christi led the agency in becoming nationally recognized and certified by The Joint Commission. Joint Commission certification is recognized nationwide as a symbol of quality and safety that reflects an organization’s commitment to meeting certain performance standards.

What nursing personally means to Christi, "For me there's so much joy in nursing. You touch the lives of so many incredible people, their families, their stories — and their stories are wonderful. I once cared for a lady who lived to her 100th birthday and although she had a long list of medical complications, she was alert and oriented. She quickly became someone I longed to visit, even on my days off. Her heart warming stories and priceless wisdom drew me close. Her grown children lived out of state and they visited when they could, but I knew her days grew long and lonely. As her condition deteriorated I found myself at her bedside more and more. What a privilege it was holding hands with her while she traveled the journey to a place of everlasting love and peace. I'll never forget you, Mildred. You taught me the art of being a nurse."
