“Sometimes, the best marketing plan is to do a great job for your current customers.”

Quality Over Quantity

We believe the best way for us to build our business is to successfully help you build yours. By taking on less clients and focusing on the success of our clients, we build long-term partnerships. This model has served us well and is the reason for our strong customer retention.

Our model is to focus on one website at a time, so your site is completed rapidly and you get the best service. This also saves you time and money when working with us.
The success of our company should be based on your success. We believe that if you are pleased with our services, you will tell other businesses about us. We plan to always build/maintain our reputation by offering a great value and great customer service to our clients.

Because Your Business Deserves The Best

No subcontractors | No commission sales reps

Lake Cook Marketing is a small team of web developers/designers who also handle sales, social media, and visit our clients. We visit you in person to learn about your business and take authentic photos for our sites. Many marketing companies have expensive sales reps and subcontract their website work. All of these extra people increase the costs and makes your site more expensive. You can receive a brand new and competitive website, at half the price of having it built elsewhere. With Lake Cook Marketing you will get the quality service and benefits of a large agency but at a fraction of the cost.

Our customers never have to choose between price and quality!

Your business cannot afford to be without a strong website!

“I come from a small business family and I have tremendous respect for entrepreneurs. Every business begins with a person taking a chance and investing in themselves. It’s very difficult to start a business and most people never try. Local businesses need our help more than ever. Between online retail, superstores and everything becoming a commodity; it is harder than ever to compete. I founded Lake Cook Marketing with the intention of supporting local businesses in any way that I can.”- Greg Martin Letellier Founder of Lake Cook Marketing
