About The Burwin Institute
Established 1984


The Burwin Institute was established in 1984 to provide quality home study courses in diagnostic ultrasound applications. Burwin courses provide a means for technologists to learn theory in a structured fashion needed to challenge the Registry examinations. It is recognized that various institutions offer short courses and seminars for Registry preparation but many technologists do not have the time or finances to attend these types of programs. Studying with home study courses is a proven and effective method of learning.

Burwin courses are comprehensive and current. As such, they are an excellent way of obtaining continuing education points for Registry maintenance.

All our courses are evaluated by the Society of Diagnostic Medical Sonographers (SDMS) and accepted for educational credits or units by the American Registry of Diagnostic Medical Sonographers (ARDMS), American Society of Radiological Technologists (ASRT), Cardiovascular Credentialing International (CCI), Sonography Canada, Society of Vascular Ultrasound (SVU), State of Florida Radiologic Technologists, and state of California Board of Registered Nurses.

Burwin Course Authors & Managers

Chris Harrington - RT(NM), RDMS, RDCS, RVT

Hello! It would be my pleasure to provide some help and instruction through this home study course.

I have been teaching ultrasound both clinically and in the classroom since 1990.

I am presently employed as the Program Coordinator for the Diagnostic Medical Sonography program at Red River College of Applied Arts, Science and Technology in Winnipeg, Manitoba, Canada. I am the author and instructor for the Burwin Institute Sonography Principles and Instrumentation course.

I truly enjoy my job, especially the challenge of teaching Physics and Instrumentation. The mere mention of the word "physics" causes many students to panic. But I believe physics can be fun, understandable, and most importantly, relevant to daily clinical practice. If you can approach physics with an open mind, I know you will surprise yourself.

Jenna Wiebe - BHSc, RDMS

Hello. My name is Jenna Wiebe and I am the course author and instructor for the Burwin Institute’s Breast Ultrasound course.

I have been working in the field of Diagnostic Ultrasound since 2005. Over the years I have gained experience performing a variety of diagnostic ultrasound exams and assisting with interventional procedures in both an acute care hospital and private clinic setting.

Throughout my career I have had the pleasure of teaching sonography students in the clinical setting and assisting other registered sonographers as they train in new specialties.

I look forward to helping you reach your personal and professional goals as well.

Jennifer Kressebuch - BHSc, CRGS

Hello and welcome to the Burwin Institute. I am the course author and instructor for the Burwin Neurosonology courses.

In 2015, upon successful completion of the Sonography Canada Generalist credentialing exam (CRGS), I began working at the IWK Health Care Center, a large regional teaching hospital that specializes in pediatric, youth and women’s care.

I hope that you enjoy the courses and do not hesitate to ask questions and provide feedback!

Margaret Corbett - RT(R), RDMS, RDCS, RVT, RMSKS

Hello. My name is Margaret Corbett and I am the author and course instructor for the Burwin Institute home study course in Musculoskeletal Ultrasound. The primary focus of the course is to cover the material required to pass the credentialing examination in this area.

I have worked in ultrasound since 1983 and am registered in Musculoskeletal Sonography as well as Adult, Pediatric and Fetal Echocardiography, Abdomen, Ob/Gyn, and Vascular Technology. I am presently employed full time as Ultrasound Training and Development Lead in a busy private practice. My teaching experience began in 1979 in Radiography.

My initial experience to teaching through distance learning was a series of courses in Radiologic Quality Control. I also have experience giving registry preparation seminars in cities throughout the US. I have been with the Burwin Institute since 1992.

Marie Hadfield - RN, RDMS, RDCS

Hello. My name is Marie Hadfield and I am the author and course instructor for the Burwin Institute home study course in Fetal Echocardiography.

I started my nursing career working on the high-risk labor and delivery unit at Health Sciences Centre in Winnipeg, Manitoba. I have worked as a nurse sonographer in Fetal Assessment at Women’s Hospital since 1997.

My areas of interest include fetal echo, Rh disease, fetal intervention, Doppler evaluation of growth restriction and monochorionic twin pregnancy.

I enjoy my job very much, particularly the challenge of providing expert family centered care to families whose pregnancy is high risk. I enjoy teaching and have presented both nationally and internationally.

I am very passionate about ultrasonography and I am excited to assist students to succeed as a diagnostic medical sonographer.

Shelley Guenther - RDMS, RDCS

Hello. My name is Shelley Guenther. I have worked in ultrasound since 1987 in various capacities, and still find the technology challenging and rewarding.

I currently work as an ultrasound applications specialist so I am always exposed to the latest technologies in ultrasound. I am fortunate to be in touch with key people in the field which enables me to stay current in the field of echocardiography.

I look forward to being of assistance as you make your way through the Burwin Home Study Courses in Adult and Fetal Echocardiography.

Stuart Gibbs - BSc, FCSDMS, RDMS, RDCS, RVT, RT(R)

Hello. My name is Stuart Gibbs and I am the author and course instructor for the Burwin Institute home study course in Vascular Sonography. My course covers the material required to pass the credentialing examinations in the vascular credential.

I qualified in 1987 and still find my work interesting, exciting, and challenging. Currently I am working at The Abbotsford Regional Hospital and Cancer Center in British Columbia, Canada. I also work as an applications specialist.

My interest in ultrasound has extended to serving in professional societies as a board member of Sonography Canada and president of The British Columbia Ultrasound Society (BCUS). I am aso a Fellow of Sonography Canada.

Teaching ultrasound continues to be a rewarding experience for me whether it is presenting at national conferences, provincial society meetings or teaching students/residents in my department. My areas of expertise include Vascular, Echocardiography, Neurosonography, MSK, Abdomen, Obstetrics, and Gynecology.

I am sure you will enjoy the Vascular Technology course.
