Clients Testimonials

“Our company has a long-term relationship with Oak Tree Engineering LLC. I was initially impressed with their ability to provide engineering expertise on a variety of small projects related to plastics manufacturing that needed a very quick turnaround. Over the past 6 years OTE has been involved in many projects for us that have required extensive engineering design skills and have also taken on project management responsibilities for several projects. We have also entrusted two of our plant expansions projects for OTE to manage.

We have been very pleased with the results on these projects and in particular the level of professionalism that OTE brings. They have always ensured clear communications with the project teams; they deliver to the established milestones and have always taken safety very seriously. All of the projects OTE has worked on for Asahi have been delivered without any safety or quality issues.

We continue to work with OTE, and they are currently executing a large project with us and are being considered for other projects. We sincerely thank OTE for their dedication and in particular Mr. Sharma for his leadership of this organization. We look forward to a long and continued future together.”

“Subodh, we would like to thank you for the safe and professional work conducted at our Jackson facility during our Line 3 replacement project. Safety is a core value at Basel! and we were extremely pleased with the attention to safely, prompt response to concerns and the open feedback to help us further improve our own performance. The two months project was completed without injury, on time and within budget. Feedback from all levels of organization was very complementary of your work and interfaces with both our own employees and contractors. The line is running extremely well.

We look forward to a lasting mutually beneficial relationship, for both capital and reliability driven projects.”

It is with great pleasure that I write this letter of recommendation for Oak Tree Engineering LLC located in Monroe Michigan. Oak Tree Engineering LLC has provided engineering design and development of production support equipment for us since 2014. To date we have 4 designs and 3 pieces of production support equipment in use that was designed and delivered by Oak Tree Engineering LLC.

Oak Tree Engineering LLC has impressed me with their attention to detail and professionalism. During the design phase, they send a design team to our site for a consultation to ensure the scope of the project is fully understood. Once the scope is defined, draft copies of the design is shared and communicated to us either in person or by email until the final design is approved. Once approved, they offer the option to have the equipment manufactured and delivered directly to our site.

All equipment designed and delivered by Oak Tree Engineering LLC has been on time or exceeded the discussed schedule. All pieces of equipment provided are robust and functioning well without incident in our production process. I highly recommend Oak Tree Engineering LLC for engineering consultation & services and support their effort for certification.
