Mike rebuilt my client's website (a remodeler in Vancouver) in HubSpot. The client's original CMS did not allow for customization...it was really bad. Mike rebuilt the site in HubSpot using a theme and customized it to look almost identical to the client's original website. The biggest improvement was that the client's site is now drag & drop, easy to edit, and we have the base theme on which to build future content and pages.

Mike was easy to contact and quick to meet. It required minimal communication and oversight to complete the project to our satisfaction.

I found a minor error after the website was delivered. (form fields didn't display properly on mobile) - but to be fair, I missed it too! Mike fixed it in short order. But it's important when working with any developer to check the functionality of your site on all platforms - a lesson learned on my part!
