Our Team
Cassandra Buzard
I am a Registered Nurse with over 23 years of experience, along with several years working as an ER technician prior to becoming an RN. My background includes pediatrics, emergency medicine and orthopedics. Over the past few years I have also gained experience providing IV hydration therapy, helping clients support their overall health and wellness.
Outside of work, I enjoy traveling, spending time with family, staying active, paddle boarding and recently discovering a love for pickleball!
I am excited to be joining Colorado Mobile IV Medics and look forward to providing safe, high-quality hydration and vitamin services to the community!

Hannah Martin
Cameron and Hannah, both Registered Nurses, met in the emergency room and are now happily married with 3 beautiful kids! They both have a love of adventuring whether it is backpacking through the Colorado mountains, exploring the beaches of Kauai, or getting lost aboard together.
Along with a love of life they have a love of caring for people. While skilled ED nurses caring for people in crisis, they wanted to be able to care for people before they have to go to the emergency department. This made Colorado Mobile IV Medics the perfect place for them to provide compassionate care making people feel their best all of the time.
They love Northern Colorado and are excited to care for their community!

James McWilliams

I am also a Realtor and high school football coach. I enjoy helping people in those aspects as well!
I am a father of 3 adult children and I have one grandson so far. Family is everything to me and I treat my clients as my family!
Gretchen Sulley
Registered NurseAs a Denver native, I’ve spent the last 7 years as a "local traveler" RN, which is another way of saying I’ve worked in just about every patient setting you can imagine. From high-acuity units to specialized patient populations, I’ve seen it all—and I’ve brought that clinical precision to the world of mobile hydration.
When I’m not hanging IV bags, I’m likely shouting words of encouragement as a high-intensity Pilates coach. I believe in recovery that works as hard as your workout.
My home life is a bit of a circus, shared with my husband, my son, a busy high school athlete, two bossy Dachshunds and one sweet Golden Retriever.
I’m thrilled to be a part of the COMIVM team and can’t wait to help many patients reach their wellness and recovery goals.
Jay Heffer
Licensed ParamedicMy name is Jaylynn Heffer, though I am commonly known as Jay. I bring eight years of experience in Emergency Medical Services, with the majority of my career spent serving communities in New Mexico. During that time, I also earned my bachelor’s degree in Integrative Medicine, further strengthening my commitment to a comprehensive, patient-centered approach to care. In January 2025, I relocated to Colorado and I am excited to continue my journey in a new community.
My goal has always been to help others, and I look forward to doing just that while getting to know and serve the community I now call home. I’m passionate about helping people build healthier, more balanced lives by supporting them in reaching their personal wellness goals. That’s why I’m especially excited to be part of the CO Mobile IV Medics team.
Outside of my professional role, I enjoy staying active and spending time with family as much as I can, I travel back to New Mexico frequently and love being on the road, I also enjoy reading, crocheting, and spending time with my two dogs.
