Dr. Susan Sipay, MD

Dr. Susan Sipay MD is the Founder and Lead Medical Doctor of Functional & Metabolic Medicine of Colorado.

Roughly 20 years ago, I graduated from Rush Medical College in Chicago, Illinois. After graduating, I began practicing medicine in the Emergency Room before transitioning to urgent care. I truly love taking care of patients. However, I began to realize that 15-minute appointments do not get allow enough time to figure out complex issues.

I love that I have time to be able to take a detailed history. I can’t tell you how many times I knew there was an underlying cause to an issue, but couldn’t take the time I needed to figure it out in the quick-paced emergency room setting.

Luckily, I learned about Functional Medicine! I love that I have time to be able to take a detailed history. I can’t tell you how many times I knew there was an underlying cause to an issue, but couldn’t take the time I needed to figure it out in the quick-paced emergency room setting.

There is hope. Together, we can work towards a better lifestyle, a better enjoyment of life, or whatever your goal may be. I am excited to start this journey with you,

TJ McCollum PA-C

TJ McCollum PA-C is the Founder of Colorado TRT and expert in hormone treatments for men at Functional & Metabolic Medicine of Colorado.

Dr. Sipay and I have worked together in the urgent care setting. Our paths recently converged in hormone health. Although, I work in trauma and urgent care, my passion lies with helping men with their health issues.

TJ earned a Bachelor’s in Biology from George Mason University and a Bachelor’s of Nursing from Troy State (cum laude). He would later graduate from PA school at Red Rocks and then go on to earn a Master’s Degree at St. Francis University.

TJ trained in mainstream medicine, then found alternative medicine through his 20 year career. He practiced as an ER Nurse at Children’s Hospital and later at Saint Anthonys Hospital.

Later having worked with one of the leading urologists in town, TJ began learning how to treat treat low-testosterone with testosterone pellets, which would grow to over 400 clients under his treatment.

He met with his patients weekly, while most practitioners may see their patients every 3 months. He was able to see the progress over time. This also helped him deal with just about every side effect of the therapy. His patients were so happy with the way he treated his patients they encouraged him to start his own clinic — Colorado TRT.
