Dedicated Pro-Account Manager

Get as much or as little help as you need. Tired of hearing your account manager is "not available" or that whoever picks up can't help? At Great Lakes, anyone on the team can assist with product knowledge, inventory, install guides, lead times, specs, and more. That's the difference with a family-owned business — chances are, you'll be working one-on-one with an owner.

Showroom & Product Selection Help

We help our pros' residential clients with product selections and kitchen cabinet renderings in our Grayslake showroom. We don't offer installation or remodeling to homeowners — we sell products and refer them to our trade partners, which is what we're all about. We can meet virtually with anyone, and we work with commercial procurement departments on product selection and design details too.
