About Us

How it all Began…

A very fortunate chain of events...
Earl Z. and Ken V. - owners of Lisbon Creek Systems

Ken grew up in a neighborhood south of Milwaukee, and has a profound love for nature, hunting and the outdoors.  He enjoys his life’s work as a successful salesman. Ken enjoys meeting business owners and working with them by listening to the challenges presented and finding successful solutions.   He was known as the “Security Guy,” selling security cameras and alarm systems.

Ken has developed thousands of relationships with people who appreciate his reputation of good-natured honesty and integrity.

Earl is from a MKE suburb where he enjoys raising a large family on the same farm where he had a wonderful childhood. “Lisbon Creek” flows through this special property which has always symbolized strong values of love, faith and integrity.

He has always loved technology, and developed professionally as an installer, design engineer and product demonstration specialist. His natural aptitude for technology afforded him expertise in audio, phones, IT and security.

Ken and Earl met while working at a local security company.  Ken was asked to train Earl in sales, and share his commissions. This seemed odd, but being open to new opportunities and having just been hired he wouldn’t question.

What he didn’t anticipate was that when he brought Earl and his expertise to sales presentations, it became clear that their partnership was dynamic. They gained more projects and earned new clients relationships. During this season they found a gap between their current offerings and their customer needs.

Clients began asking for more services, and a comprehensive technology company was founded, Lisbon Creek Systems.

A few weeks ago , the whole security system of the clinic i work at went down. I contacted Jake and he assure me a quick response to trouble shoot and identify the problem. Afterwards, Jose and Keith came to the rescue , trouble shoot my system , found the problem and resolve it right away. They save my skin that day and I would be for ever grateful. I will recommend Lisbon creek system to anyone who wants a quick, responsive solution.

We had Lisbon Creek install the phone and security system for our new build dental practice, and couldn't have been happier. From start to finish, their communication with us was clear, efficient, and professional. They worked with our other contractors to make the process seamless for us. They listened to what we needed and made sure we were happy with the result. Michael did amazing work coordinating a lot of moving parts with a tight timeline. I highly recommend Lisbon Creek!

I work at the Milwaukee Rescue Mission as the IT Strategy Manager. We worked with Lisbon Creek Systems on replacing and installing a large number of our outdoor cameras. The 8MP cameras we purchased had excellent resolution for a reasonable price. The project was completed ahead of schedule and the gentlemen (Donovan and Lee) sent to do the work arrived early, were professional and friendly, and worked flawlessly with our team. We plan on working with LCS in the future and highly recommend them.

Was on the fence for awhile about upgrading my phone system. The team at Lisbon Creek was ready to answer every question I had and walked me through the whole process. After the installation, they were easily reached over the phone and were available to help me navigate my way through the new phone system. Quality, Affordability and Timely. Rarely if ever, do you get all three!

I want to start by saying our construction project and restoration of an historic 27,000 Sq. ft. 128 year old building was very unique and extremely challenging. I was completely in the dark when it came to finding a company that could rise to the challenge of our complicated low voltage, security, telephone and audio visual needs all in one. Enter Lisbon Creek on a chance encounter! From beginning to end Ken, Earl, Eric, Jose & Matthew have spent extra time learning our exact needs and constantly coming up with solutions for what will work best for our business. Their multiple site visits, communication, customer service, attitude and patience were very much appreciated from someone (myself) who does not have a lot of low voltage & equipment knowledge. I would also like to mention that they worked very hard to find a solution that worked and stayed real close to my budget! I anticipate that we will need to add to and tweak our systems as we get used to our new surroundings, but I am 100% confident that we have chosen the right team to navigate us into the future and that their great customer service will not stop after our final payment!
