I just wanted to thank you and your team for a job well done over in Spokane. The drilling wasn’t ideal, but Kevin Bacon and Rayon Darling did an excellent job and were a pleasure to work with. I was also very impressed with how they maintain and take care of their equipment. It was good working with you guys and I am sure we will see you guys again soon.

Field Exploration Supervisor TE-3
I work with many drilling companies around the United States, and Holt Services is the one I compare others to in regards to quality of work and expertise. I really appreciate their willingness to make it happen regardless of what the challenge is!
Jim Bailey, Seattle, WA
Everything went really well, and Randy and John were great to work with. I appreciated their communication leading up to their arrival, and they were friendly, conscientious about maintaining a clean work site, accommodating to my needs, and safety oriented. Overall, they were a great crew to work with on this project.

It was a pleasure working in the field with Kevin and Jacob last week. They were skilled professionals, did great work, and were enjoyable to work with. I look forward to working with them again.
Mark K.
Geotechnical Engineer
I was the geologist in the field for much of the project and wanted to let you know your crew was fantastic. I would go as far as to say one of the better crews I’ve worked with. They were always showing up with positive attitudes, ready to work hard, and worked with me as a team. It’s very refreshing to see a crew so easy to get along with.

Thanks for sending these over Jeff. The logs and DDA report look accurate. Chris and Reggie were great to work with. They kept the parking lot disruptions to a minimum, fought some tough DP drilling at depth, and cleaned up everything nicely at the end. There are several wells on the property. These two have the best surface completions.

Following completion of the work, I heard from my field team that Javier Anguiano was one of the best drillers our Anchor QEA team has worked with, and we have worked with many over the years. They also indicated that Brody Schwartz provided excellent support.
Ryan B.
Principal
Just wanted to commend Steven and Spiker on a phenomenal job out at Melrose. They got it done under time and were great to work with (as always). Their great work ethic and positive attitude make projects fly by. It’s always a pleasure to have them as part of the team. Please pass along the praise to whomever needs to hear it.
Samantha E.
Project Geologist
We are all down at the site. I just wanted to say it was a pleasure working with Steve and Mike on this project. Steve is very knowledgeable and really helped to make this a successful project. I wanted to pass on kind words about you guys in the field. Thank you for the drilling support.
Thomas M.
Operations Manager
Chris and the crew of John and Robert were outstanding in all aspects of their work: prompt, professional, safe, collaborative, good-natured, and skilled. I was impressed by how well each knew their job and how well they worked together. It was a pleasure working with and watching the teamwork. I’d want them on any project.
