Dr. Alrich L. Gray // Central Montana Heart & Vascular Institute

Tanna Schroetlin
Lead Medical Scheduler

I was born and raised Great Falls, Montana girl and feel blessed to have been able to raise my girls here as well. I have spent my career helping others in the medical field and over the last 35+ years, I have worked in ENT, Ophthalmology, Pediatrics, Family Medicine and now Cardiology.   I have held positions such as Receptionist/Medical Scheduler, Medical Tech, Certified Optician, Surgical Assistant, Registered Medical Assistant and a Children’s Autism Trainer.

I own a small Essential Oil business where I enjoy teaching workshops and educating on natural solutions. I love the outdoors, camping, hiking, sporting events (Go Cats!!), Hot springs, concerts, playing with the flowers in my yard, and spending time with my girls, family and friends!

Seems I am starting a new chapter in my life.  My youngest just turned 21,  and I am experiencing a bit of the empty nest syndrome.  While I now have to take out my own garbage...my grocery and water bill have gone down!

I am looking forward to spending the rest of my career here at Central Montana Heart  & Vascular Institute!

Shannon has been in the medical field for 25 years, with 19 years as a volunteer emergency medical technician serving the Sun River Valley Community.

She has worked as a registered nurse in Cardiology, both inpatient and clinic settings, for the last 15 years.

She earned her bachelor's in nursing and is a basic life support instructor and educator on congestive heart failure and stroke as well.

She enjoys time with her young family at home on her little animal farm, skiing, and snowmobiling. She also loves to read and cross-stitch.

"Patient care has always been my number one priority. I have loved having the opportunity to care for patients in different healthcare settings as well as their homes and watching them return to better health. I am excited and thankful to be a part of CMHVI and work with Dr. Gray, where patients and their care are #1."

Megan Brinka, RN
Clinical Staff

Megan Brinka is a BSN, RN from Great Falls, MT. She found her love for cardiovascular medicine when she started working in the Progressive Cardio Vascular Unit at Benefis right after graduating from Montana State. She loves medicine of the heart because she admires the comprehensive affect it has on the rest of the body. If you understand how the heart works, you can then have a greater understanding of the rest of the human body and its many diverse functions. When she’s not working at the clinic, or checking in on her patients in the hospital, she can be found snuggling with her kitties or one year old niece Kinsley. She has a love for Montana and its natural beauty along with the small-town closeness you feel with its residents anywhere you go. Megan would love to go on to obtain her Masters of Nursing where she can continue to learn and become an expert on all things cardiovascular.

Clinical Staff

I have been a CMA since 2018 working in various specialties, including, Family Practice, OBGYN and Pediatrics before coming to Cardiology. I have lived in several states before coming to Montana including Michigan, Wisconsin and Pennsylvania. In my spare time I enjoy reading, spending time with family and friends, hiking and playing with my dogs.
