Wellen Construction is a Southborough, Massachusetts custom home builder that also spends much of its time building out dental, orthodontic and dermatology offices. The company says founder Rob Wellen started it in the early 1980s and later brought in his cousin Charlie Gadbois, who now leads the firm; it describes more than 35 years building for clients across New England. Its written record runs from 2014 to 2026 across Google and Houzz — 31 reviews in all, none below five stars. Medical and dental practices keep hiring the same team: a dermatology practice said in an August 2024 review that it had just finished a second project with Wellen and hoped to do a third, and another practice owner wrote in a December 2023 review that after a 2019 remodel they were bringing Wellen back for an expansion. Named project managers — Justin Lopez and Dan Luthern on a dental-office build described in a March 2026 review, Diego Solimine on a 2023 dental-office expansion, Rob on two oral-surgery offices in a 2023 review — come up by name across separate, unconnected clients. On the residential side, a 2020 Boston Magazine feature named Wellen as the contractor alongside architect LDa Architecture & Interiors, and a 2025 post described the firm mid-way through a full renovation and expansion of a family home in Cambridge. Its Massachusetts home improvement contractor registration (#173532) is active; BuildZoom separately lists a Massachusetts Construction Supervisor license (#CS-107363) for the company. Wellen is a strong call for a ground-up custom home, a major addition, or a commercial medical-office build-out — ask up front which project manager will run the job and how they handle changes once work is underway.
“Here's a look around a current Wellen project, which is a full renovation and expansion of a family home in Cambridge.”
“The home was originally built in 2002 by Wellen Construction (Wellen). As part of the original construction, Wellen installed rope lighting manufactured by Wangs in the house.”
“Architect: LDa Architecture & Interiors. Contractor: Wellen Construction. Interior Designer: Nina Farmer Interiors.”
“The extensive list of collaborators for this project includes LDa Architects, Wellen Construction, Phil Mastroianni Landscape Construction, and Boston Tennis Court.”

I had an excellent experience working with Wellen Construction while building Heart of Hingham Dental Aesthetics. Their entire team was incredible - fast, efficient, and extremely thorough throughout the entire process. The quality of the work and attention to detail really stood out, and they kept everything moving smoothly and on schedule. My project manager, Mark Ventura, was truly fantastic to work with. He made the entire process feel easy and stress-free, was always responsive, and consistently advocated for me whenever needed. It’s rare to find someone who is both highly professional and genuinely great to work with. I’m so grateful for the work they did and would absolutely recommend Wellen Construction to anyone looking for a reliable, high-quality construction team.
We had a fantastic experience working with Wellen Construction and couldn't be happier with the end result. Dan Luthern and Justin Lopez were an absolute pleasure to work with from start to finish. They were professional, communicative, and genuinely invested in getting things right. Justin was on site early every single day, which set the tone for the entire project. He thought of every single detail and made sure things were executed perfectly. The consistency and commitment made everything run seamlessly and gave us real confidence that the job was in good hands. It's rare to find a crew that shows up not just on time, but ahead of schedule. Dan was equally great -- easy to reach, clear in his communication, and always on top of the details. Together, they made what can often be a stressful process feel smooth and straightforward. We're thrilled with how everything turned out and would highly recommend Wellen Construction to anyone looking for a team that takes real pride in their work. We'll absolutely be calling them again for future projects!
We had an excellent experience working with Wellen for the construction of our new dental office. From the initial planning stages to the final completion, their team demonstrated outstanding professionalism, organization, and attention to detail. Wellen clearly understands the specific requirements of dental clinics and built the space with an efficient layout, proper construction systems, and the correct infrastructure for dental equipment. Every aspect of the project—from plumbing and electrical work to equipment integration—was handled carefully and professionally. A special thank you to Shawn and James, our main construction representatives, who were incredibly helpful throughout the entire process. They were responsive, knowledgeable, and ensured that everything progressed smoothly and efficiently. Shawn, who was our on site manager make sure the office is completed in proper form and worked above and beyond to get my dental office permit. Also, James make sure even after construction is finished, that after care or any minor issue is solved on their hand. The project was completed efficiently, communication was clear throughout, and the quality of the work exceeded our expectations. Our office is functional, modern, and designed to support a smooth workflow for both staff and patients. Lots of my patients complement how beautiful my office is built. I highly recommend Wellen to anyone looking to build or renovate a dental clinic. Their expertise in dental office construction truly shows in the final result.
Wellen was a fantastic group to work with. They genuinely care about their work, they do not cut corners, and do a great job keeping you informed about their progress. I felt that they listened to my concerns and helped me troubleshoot any unexpected scenarios that popped up. In terms of timeline, they were very good at setting reasonable completion dates and we stayed on schedule. I will be looking to them again when I'm ready to expand my business further!
My wife and I had a great experience working with Wellen. Working with Justin Lopez and Dan Luthern was very seamless. They were always available to answer our questions. Justin had gone above and beyond with his duties. Very professional. We very much informed throughout the process. They also helped us very much communicating with the local government for our permits. I would highly recommend them to anybody who's looking to start their clinics. Cannot say enough great things about them.
