J. Timothy Builders, Inc.

About Us

We're Jon and Christine and We Look Forward to Meeting You!

We Really Enjoy What We Do!


     Jon Wittrock attended the Milwaukee School of Engineering (MSOE). He began his experience working in the construction field as a high-end carpenter for Orren Pickell Builders. Through education, experience, and unique natural talent, Jon mastered the skills needed to build a high end quality home and quickly advanced in the building industry, becoming the successful General Contractor he is today.

     Christine, after earning her masters degree, became an integral part of the business. Along with being available to our homebuyers on a daily basis, she is often working behind the scenes to guarantee a smooth and enjoyable experience for our clients throughout the project. 

Why We Started J. Timothy Builders, Inc.


 We incorporated our business in 2000, because we, ourselves, found such a need in the industry for custom homebuilders who provided a quality product at a competitive price, along with outstanding personalized customer service. 

Our clients  are constantly telling us how easy we are to talk to and work with. 

Our Experienced Team


Building a new home is exciting but can be overwhelming.  Not only do we make the process easy, we also make it fun!  We want you to enjoy your project every step of the way and in order to do that, you must trust that your builder is looking out for your best interest at all times, while keeping your budget in mind.  We are an experienced team working together to make your building experience smooth.  If you are looking for a builder who will just switch from subcontractor to subcontractor looking for the best bottom line, we will not be a good fit for you.  We are proud of the subcontractors we work with and the quality work they do.  They are an integral part of why your home will stand out from others.  While we always negotiate for the best pricing for our clients, we are not willing to sacrifice quality.

Our practical approach comes from our own experiences building our personal custom homes


Our decision to use J. Timothy Builders, Inc. for the construction of our new home was the best one we’ve made.  They are professional in every sense of the word. They are extremely knowledgeable, fair, and have guided us effortlessly through every step of the building process, taking much of the pressure off our shoulders. The pride and care that J. Timothy Builders, Inc. takes in the construction of their homes, is evident in the quality of the finished product.  If we were to ever build another home, we would absolutely call on J. Timothy Builders, Inc. again!

Being in the business myself, I have had many experiences with contractors, and J. Timothy Builders, Inc. is by far one of the most professional contractors I have worked with!

First of all, I want to thank you and Jon for the amazing house that is transforming before my eyes.  It is more than I deserve and has exceeded my expectations…

I can’t even begin to take it all in when I go there to check it out.   I can’t believe that I actually will live in that home some day.  Thank you so much for creating my dream! Nobody builds a better house than you and Jon and no one comes close to your vision and quality.  I am so blessed. 

Thank you from the bottom of my heart!

"Karen and I would like to sincerely thank you for the dedication, commitment, and quality workmanship that you provided in completing our project in WilliamsBay.  Working with you both was an absolute delight. 

Jon, your commitment to staying on task and on goal showed through in every situation we uncovered.  We realize that this may have been one of the more difficult projects you have completed.  While building a home on the side of a hill is no easy task, you continuously plowed on with a great attitude and a vision for the completed project.  We were very happy with the way your crews and subs tried to work with us and guide us to what we believe is a simply outstanding home.  In addition to that you should be very proud of the relationships you have established with them.

Every single one of the people we worked with had the highest regard for you as a boss and friend.

Christine, thank you so much for keeping us on task.  Your record keeping and approval process is the most detailed and complete project management process I have encountered on any project.  Your helpful nudges kept Karen and I moving and always helped us stay ahead of the next decision.

We are delighted by, and proud of, the relationship we have established with J. Timothy Builders and would welcome the opportunity to provide any references you may request.

Thanks again and especially thanks for treating our project like you were building it for your own family!"
