Chris was a little early for our appointment, however, he was very deliberate in the inspection of my home. He provided excellent information about the status of my current insulation and recommended the best method to meet my particular needs. He was very upfront about the pricing and possible arrangements. Although I was not prepared to go forward with the project at this time, his patience and calm demeanor was reassuring and refreshing. Thank you Chris for your time and patience.

Ben Schaefer did an outstanding job and made the whole process easy from start to finish. He was professional, knowledgeable, and took the time to explain everything clearly. You can tell he genuinely cares about doing the job right and making sure his customers are comfortable and confident with their mobility solutions. The installation was smooth, and he paid close attention to detail. I highly recommend Ben at HomePro Mobility to anyone looking for reliable service and a trustworthy professional.

Needing a chairlift to accommodate my mom was a necessity in our new home as the only shower access is on the second floor. Emmanuel came to our home and walked us through the entire process. We were able to agree on a solution that would work perfectly for our home, family, and budget without settling or undercutting our needs. Overall and extremely pleasant experience. We are grateful and excited to see how the solution works for my mom.
