Brennan Associates is here to support your RF/Microwave needs!

Social Distancing, Sheltering-in-Place, and even Mfg. Rep Distancing… all critical actions to help stop the spread of coronavirus. We know you all love to see Sales Reps, but we also know many of you are being asked by your company to avoid face-to-face interactions unless absolutely necessary. With that in mind, we are keeping our distance until this serious situation is under control.

In fact, a few of our manufacturers have actually closed down for the next few weeks due to shelter-in-place requirements mandated by local government. They are doing everything possible to continue support for US Government Requirements and all customer needs.

However, we want you to know that we remain committed to supporting your RF/Microwave component needs during this uncertain time. We are available by telephone, email, text or through our website to support your needs.

So, to all our friends and loyal customers, please stay safe!
