Eastside Environmental is great to work with and I'm definitely looking to do business again in the future. Kellen is great to work with and his co-workers/assistances are very professional as well. Very honest and follows up on services performed. As a homeowner it can hard trying to decide which company to conduct business with in this type of field. As some won't return calls or perform subpar services. I didn't get that from Eastside, instead I received nothing but outstanding service from Eastside. And also no inflated prices after the services were performed. At this present day in time it seems challenging to find honest services and I feel that Eastside delivers highly in that area. Keep up the great work Eastside. Federal Way, WA . Anthony

Kellen, helped us with our critical area delineation. He was very responsive and efficient. He made the process really easy and got our project done ahead of schedule. We would definitely recommend him to anyone looking for an Ecologist!
I'm impressed by the quick turnaround of a critical areas delineation for a 5 acre plot. By far was the fastest part of the permitting process. The report was detailed and thorough. Kellen answered any questions I had along the way. Highly recommend.
Kellen is very professional and it is clear that he truly cares deeply about the impact that the work he does makes on the environment and his clients! He is my go to recommendation for any wetland consultation a person may need!
