Veronica L. Ritchey, FNP-C

My name is Veronica Ritchey and I am one of the Nurse Practitioners that comprise University Family Medicine Clinic. I am one of the newest members to this wonderful team and am happy that we have such a family centered group of people working together to make this organization run smoothly and efficiently. Although I am one of the newest members of this team, I have been in the Nursing profession for over 22 years and have a vast amount of experience in many different areas. I am originally from Missouri but have chosen to call Colorado my home. My family and I love to be active in sports and outdoor events as well as spending time with our friends and family.

I started my career in the US Army as a Medical Specialist in 1992. I worked in Emergency Medicine in the Emergency Room and on the Ambulance team with National Certifications. This is what lead me to Pueblo, Colorado in 1995. I began my degree at the University of Southern Colorado graduating with my BSN in 2000. I later completed my degree at The University of Colorado at Colorado Springs, Beth-El College of Nursing with my Masters of Science in Nursing, Family Nurse Practitioner, as well as course work in Nursing Administration. Although not a native, I obtained my degrees right here in the State of Colorado where I continue to reside and care for my patients.

I worked at Parkview Medical Center for over 14 years in multiple different areas as I obtained my education and climbed the ladder in nursing. My specialty was in the Neuro Trauma ICU where I worked with acute, critically ill, and injured patients with traumatic brain injury, and spinal cord injuries, as well as unstable trauma patients before they were stable enough for step down or rehab units. I also worked in the Emergency Department, Medical Surgical/Ortho, and was Charge Nurse for the floor. I also was a vital member of the implementation team that originated the JCAHO Certification in Disease Specific Care in Stroke at Parkview Medical Center. I helped educate the hospital and the community about Cerebral Vascular Accidents, strokes, and the risk factors as well as stroke prevention.

I want to thank you for investing your trust, and health with us at University Family Medicine Clinic and know that we will continue to do our very best to keep you, and your family healthy.
