Our Staff


Shelley Kroczynski B.S., R.V.T.


Shelley is the Technical Director of Desert Vascular Specialists' lab as of 2018. She graduated from the Oregon Institute of Technology in 1999 with a Bachelor's Degree in Medical Imaging, Vascular Option. She became a Registered Vascular Technologist in 2000. Over her years of experience, Shelley has become proficient in carotid, abdominal, peripheral arterial, and venous ultrasound. In her time off, she enjoys watching her teenage girls play sand volleyball and spending time with her family. 

Kari Cooling B.A., R.V.T.


Kari's path to her profession as a vascular sonographer is not a typical one. She obtained a Bachelor's Degree from Northern Arizona University in Public Relations and Advertising in 2004. In 2008, she decided to enter the medical profession and returned to school in Denver to obtain a degree in Vascular Sonography, which she says is one of the best decisions she has ever made. Kari has been with Desert Vascular Specialists since 2016. She and her husband have two young children and spend their time keeping up with them. In her time off she enjoys the outdoors: camping, swimming, fishing, boating, or riding bikes. 

Toni Mangini 


Toni knew that she wanted to pursue a career in the medical field after taking her first anatomy class in high school. In 2012, she found her calling in ultrasound. She was fascinated by the challenge of gaining proficiency in cardiovascular studies. Throughout her schooling at West Coast Ultrasound Institute, she developed a passion for learning and helping prevent the progression of life altering pathologies in patients. Toni graduated in 2014 with an associate's degree in Applied Science of Cardiovascular Echosonography. When not pursing her passion for helping patients, she can be found enjoying a good laugh over a book or out hiking in the beautiful Arizona weather.
