Terry L

Very easy to work with and flexible. Have come through for us on short notice several times when we needed security for events. The guys that show up are real pros and have been in the industry for years. It was way too much of a hassle to come up with security on short notice on our own and Trinity is a great option. Highly recommended!

Normally, I wouldn't leave a review for a janitorial cleaning company, but the team at Trinity is more than just a cleaning service. Trinity acts as a one stop shop for all our building services: janitorial, security, and building maintenance. They are a family-owned company that has a quality team and services. I can always rely on their team to show up.

The service is great. Lehua takes care of customer service needs. She is always pleasant. Sylvia has been the supervisor for the janitorial staff for many years and will always make sure you get a really good bid and does a great job of overseeing the clients' needs. The janitors do such a good job; there are very few complaints. Their rates are awesome.

The team at Trinity provided quality janitorial services for our office building. Our office is re-opening (post COVID), and we needed a deep cleaning and Sterilization, so we gave them a call. They did an amazing job - they showed up on time, and our office is sparkling clean. They offer the BEST janitorial and commercial cleaning services in the SF Bay area.
