They actually suggest things to us. They find better ways of doing things, so they really strive to give their input and their suggestions, which is really nice rather than just building something we are asking them to build.

Erin Wilson's Review Sourced from Google
The training was very good. The instructor did an excellent job of reiterating talking points with real life experiences and stories from the IT industry. I enjoyed the activities with the table groups and the hands on learning technique. I am currently on a Scrum team, and am excited to apply what I have learned from this class to our team to help increase efficiency.

Intertech did an excellent job with the Scrum Master Certification Course. The course/training itself was very good and informative. Very interactive and the instructor, Lonnie, was amazing. She had so many real life experiences to share as related to scrum.The Intertech facility and the staff were wonderful. The people who worked there were helpful and friendly and the facility worked well to hold the training.It was a great experience and I would recommend Intertech for training and certification courses.

Maggie Rottach's Review Sourced from Google
Excellent interaction from the Intertech staff from initial arrival and throughout the classroom sessions.I found the instructor to be knowledgeable on the course material for Java 8. He kept the class at a reasonable pace based on the various skill levels and background of the attendees. The coursework included well prepared materials, discussion, and awareness of the goals of attendees. For example, the instructor highlighted pertinent areas of the material knowing several attendees were candidates for taking a certification test.Additionally there was an option available to attend this class remotely via Webex. While I opted for classroom attendance it's great to know this capability exists for future reference.This was, for me, an exceptional training experience. I highly recommend including Intertech as a option for training needs.

Bradley Collins Review from Google

Bradley Collins's Review Sourced from Google
Working with the guys at Espresso Moon (Scott, Doug, Tim and Dwayne) was truly a great collaboration and experience. They didn't just throw a website together for us, they helped us to reinvent ourselves. They go out of their way to get to know you and your business to the fullest extent, and that is a quality that is not often seen. If I were to recommend a web design/hosting company to anyone, Espresso Moon would be the one and only name I give. Thank you for your service and support!
Meredyth Jones Review from Google

Meredyth Jones's Review Sourced from Google
I worked primarily with Scott, Tim and Doug to build a fairly complicated site: Paypal/credit card payments, video training modules, a graded quiz, and issuance of a completion certificate. They were the only website company that invited me to an in-person meeting and that was tremendously helpful in me understanding how they work and them understanding my goals. Large Animal Consulting & Education launched 2 days ago and the site is running smoothly. I'm very happy with the site they designed (they also designed my logos) and am looking forward to using them to support and add to the site down the road.

Caleb Schallert's Review Sourced from Google
Doug Wheeler is the owner of Espresso Moon and he has provided my small business excellent IT technical support for our website. His team helped me out by removing malicious code that was affecting my site right after the Heart Bleed epidemic last year. He got my site back up and running so i could continue business and save my online reputation. I would recommend Espresso Moon LLC to anyone in need of a new website or mobile application because they follow through with what they promise to do, on time and on budget. They are truly a pleasure to work with!

Integration testing: Assesses how the different system components interact with each other, including how data flows and how third-party systems work together
Regression testing: Analyzes the stability and functionality of the app after a bug has been fixed
