During Medical Laboratory Professionals Week, we’re shining a light on a specialized team whose work plays a critical role in patient care. Meet our in-house pathology lab team: Erica, Lance and Shianne.

At GI Associates, we’re fortunate to have a dedicated lab team right here, focused on accuracy, efficiency, and quickly getting answers to our patients. It’s one more way we’re able to provide high-quality care.

Thank you for all you do!

We’ve all grabbed something quick and convenient when we’re busy. However, diets high in processed, low-fiber foods are associated with slower digestion and increased GI symptoms.

Choosing more whole, fiber-rich foods can help support better gut health.

Try: Greek yogurt + berries + granola, oatmeal with fruit, apple slices with peanut butter, air-popped popcorn, grilled chicken on whole grain wrap, whole wheat toast with avocado. https://giassoc.org/wp-content/uploads/2025/02/GIA_High-Fiber-Diet-Handout_FINAL_02132025.pdf

March Madness brought a little extra competition around here. Not every pick was easy to digest. A lot of early upsets…hard to process. Some brackets moved fast… others got a little backed up.

Congrats to 🏆Steve our GI Associates March Madness champion and Samantha for second place!

April is IBS Awareness Month. Unfortunately, a lot of people are living with symptoms they’ve learned to ignore: bloating, pain, cramps and unpredictable issues that come and go.

It starts as “something I ate”… or “just stress”… until it keeps happening. If it keeps coming back, it’s worth getting checked out. https://giassoc.org/
