Trillium Creek Dermatology

My family had used Trillium Creek for several years for a variety of dermatology issues. I had switched jobs a few times and thus health insurance providers. The last appointment we had was on January 2024, but we were never issued a bill for this until end of April in 2025, nearly 15 months after the services were rendered. When the bill was issued, I had switched insurance providers and so it was very difficult to try to go back and make a claim, especially since we had hit our out of pocket maximum for the 2024 year, so the full amount would have been on the insurance company that was no longer our current provider. While we bear some responsibility in not having our latest insurance on file, the fact that the billing came 15 months after service made coming to a resolution nearly impossible from our side. When we spoke to Trillium Creek's billing department, they provided no justification for the delay in the billing except that it was "stuck in the system" and basically… took no fault of their own billing us for the full amount and threating to send it into collections. I contacted the company several times to try to come to resolution, but was met with no movement on their side, demanding full payment or send it to collection, not acknowledging their delay in billing had anything to do with the issue. I primarily want to warn other consumers against using Trillium Creek as their billing practices have been poor from a consumer perspective that has been using services from the company for years.
