"Not sure what I was expecting when procuring the services of a 'lighting architect.' He was responsive (in spite of some family health issues) and had some great ideas. His billing rate is probably fair. In retrospect I would have liked to sit down with him, with the catelogs, discuss alternatives and make the decision.....rather than select some of the fixtures from recommended websites. However, he was there when the final decisions were made, and we are happy with the outcome."

Lewallen Architecture, LLC
Lewallen Architecture, LLC
At Lewallen Architecture, LLC we are committed to a high level of design and excellent customer service. Great design cost no more than poor design.
"We entered a contract with Michael Lewallen for a major addition. We chose him because his bid was the lowest. Michael Lewallen, after collecting 95% of our money, with only 60% of the project completed, said he underbid the project and basically, at the point we were on our own. He breached our contract. We paid out of pocket six figures, if we hadnâ t our project would have sat, open to the elements. It is money we did not have. It canâ t be blamed on Covid because had it been completed in the contractual 8 months, it would have been done before the pandemic. Also, some of the sub contractors told us they either had a terrible time getting paid, or they didnâ t get paid at all. In order to complete our project, we had to pay the sub contractors out of our pocket, after we had already paid Michael Lewallen for the very same services. We also paid in full any change orders to Lewallen. Much of those monies were kept by Lewallen and then we had to pay again directly to the sub contractor. We talked with two others of his customers, one project sits and the other elderly couple have paid 90% as well and their project is approximately 30% completed. Michael Lewallen underbids, slow walks the projects while billing aggressively each month, and you pay because if you don't, you are afraid he will stop totally. Once he has your money, he shuts down his services. Our project was contractually promised to be completed in eight months. After 15 months, and us begging to get a roof, a garage door, drywall, painting (everything we had already paid for), he pulled the rug out on us. I have had to hire an attorney. Michael is a master salesman. His website is awesome. But it is used to draw in customers, and once you sign a contract, the nightmare begins. If you are even thinking about doing business with him, talk to someone who has signed with him for a project at least six months ago. DO NOT DO BUSINESS WITH MICHAEL LEWALLEN."

Gryphon Custom Home Builders and Remodeling LLC
Gryphon Custom Home Builders and Remodeling LLC
Gryphon Custom Home Builders and Remodeling LLC is your premier destination for comprehensive home remodeling and renovation services in Portland. We specialize in creating beautiful, functional, and personalized spaces that perfectly reflect your individual style and needs.
"Awhile back I decided it was time to replace my old, crumbling shed. After doing a search on Angie’s List, I hired Gryphon Construction because they had good reviews. The process worked, and I must say that I’m super happy with the results I got. Not only were Akeem and company great to work with, they did an excellent job, and and I’m extremely happy with my new shed. (The only reason I’m not calling it “shop” is because I didn’t have power installed). It’s solid, has a locking door, as well as a window, and looks more like a tiny house than the shed that proceeded it. And while they were here, I also had them install a new track for a broken pocket door, which involved removing some dry wall to get at the work-out track. They did a great job on that, too, and I’m very happy with the remodel. I found them to be pleasant to do business with, as well as very conscientious, timely, and they have a strong sense of craftsmanship, which, after all, is what we all want in a good contractor. I highly recommend them!"

"I contracted with TVP for engineering plans for a home addition in February, 2023. The sales person Phil McDodson, made an agreement to stay with the project through to the permit but walked away as soon as the county required additional information. At that point Janae Spinney stepped in and would not quit on me until that promise was complete. A special thanks to Joseph and Caleb for getting us through to the end. Every engineer and staff member with TVP was polite, knowledgeable and saw the job through. It was just approved January, 2025. Great company and I appreciate all you did for us!"

"Matthew Bruce exceeded our expectations. Our 92-year-old dad fell while using the bathroom and injured himself. We needed an immediate response to make the bathroom safe. Matthew responded to my request very quickly. He asked questions about the situation that showed he had the expertise we needed. He came to the house within a day of agreeing to perform the work and completed the most urgent task that day. He needed other tools to complete the installation of the grab bar drilled into the shower tiles, so he had to return at a later time. He communicated clearly when he could return and completed the task. Additionally, he cleaned up after his work and was pleasant to workMatthew Bruce exceeded our expectations.
