Karah Norton

Board Certified Nurse Practitioner

Karah Norton  

Karah, originally from a small town in Kansas, brings a special combination of caring and expertise to our vein practice. Karah excelled from the start, graduating with a perfect 4.0 from Arizona State University with a Master of Science in nursing. Karah has provided care in a variety of settings including cardiology, gerontology and family practice. Her broad clinical background is a vital asset to Advanced Vein Center, and her patients benefit greatly from her experience.

Karah’s mother suffered from painful varicose veins, which sparked Karah’s interest in modern vein treatment. Watching her mother endure painful, heavy legs triggered Karah to research what new treatment options were available. That experience with her mother blossomed into a passion for helping patients with venous conditions.  

At Advanced Vein Center, Karah provides meticulous care for varicose veins, hemorrhoids, and phlebitis. She is especially skilled at ultrasound, sclerotherapy and microphlebectomy, and is adept with other modern techniques, including infrared coagulation and direct current electrotherapy of hemorrhoids.

Her patients compliment not only her technical skill, but her warm and caring bedside manner. She has a knack for making patients feel comfortable, with her pleasant Midwestern manner. Karah and her husband Cory have three beautiful girls and reside in Gilbert, Arizona. She loves to exercise and is currently training for her first triathlon. She can be found running, biking or hiking most days of the week. Karah also enjoys reading and crafts, but most of all, she likes spending time with her wonderful family.
