The entire training class has been recorded to be made available to those who can't have the class taught at their company or who can't attend a conference. This is the entire class material.
There is a book for all of the material in the class.
Our Experience
We have taught Go to thousands of developers all around the world since 2014. There is no other company that has been doing it longer and our material has proven to help jump-start developers 6 to 12 months ahead of their knowledge of Go. We know what knowledge developers need in order to be productive and efficient when writing software in Go.
Our classes are perfect for intermediate-level developers who have at least a few months to years of experience writing code in Go. Our classes provide a very deep knowledge of the programming language with a big push on language mechanics, design philosophies and guidelines. We focus on teaching how to write code with a priority on consistency, integrity, readability and simplicity. We cover a lot about “if performance matters” with a focus on mechanical sympathy, data oriented design, decoupling and writing/debugging production software.

More About Go
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software. Although it borrows ideas from existing languages, it has a unique and simple nature that make Go programs different in character from programs written in other languages. It balances the capabilities of a low-level systems language with some high-level features you see in modern languages today. This creates a programming environment that allows you to be incredibly productive, performant and fully in control; in Go, you can write less code and do so much more.
Go is the fusion of performance and productivity wrapped in a language that software developers can learn, use and understand. Go is not C, yet we have many of the benefits of C with the benefits of higher level programming languages.

"@goinggodotnet you were amazing!!! So enthusiastic!!! Thanks for doing this for everyone!"
Kelsey Hightower (@kelseyhightower)
"Day 1 of the [Ultimate] Go workshop was outstanding! Big shoutout to @intel, @golangbridge, and @goinggodotnet for bringing this to Portland."
Katrina Owen (@kytrinyx)
"OH: "You thought you knew Go..." (You do Go? You want to do Go?) You should take this workshop. Seriously.) "
Ian Molee (@ianfoo) "If you're at @GopherCon, get yourself to a session with @goinggodotnet. Superb! Pretty sure his pic appears with the definition of "dynamo.""
Matt Oswalt (@Mierdin)
"Should be mentioned that though I am no expert, I have been using Go for about a year - and this meetup is kicking my ass."
Testimonials
Paul Yeoh
_"Today’s workshop was just mind blowing! You kept us all on the edge all day long - it was the most exhilarating all day workshop I have attended, period. The content was inspiring, moving - caused me to think deeply and gave me a lot of meat to chew on about what it is we are really doing as programmers, what an awesome day!
And most of all, I just got such a kick out of the energy which you were putting out - larger than life, it felt like you were turned up to 200%. I really took a lot from it at many levels. Thank you!!"_
Ana-Maria Lazar, Software Engineer at Sainsbury's
"Intensive crash course in Go that literally takes you to a whole new level. Not only Bill provides lots of examples and exercises to familiarize yourself faster with the language but there is also a lot of information that can be applied to other languages as well. Perfect combination!"
Susan Dady, Software Engineer - GE Digital
"Rarely will you come across a course as worthwhile as this one. I learned many things relevant and useful in my daily work and William's energy kept me engaged. I came back to work excited to get coding in Go."
Richard Stanley, Software Engineer - GE Digital
"Not only does Bill deeply understands the technical details of Go, he also can explain them in an effective, enthusiastic manner that helped me retain somewhat dry material. His passion for the language and its capabilities are obvious through out his training."
Shalab Goel, Ph.D.
"It was a pleasure taking this course — learning lot of "dry" stuff in such animated and enthusiastic environment. The exercises were spot on for building what you called as "memory muscle. I have good amount of background in conventional multithreaded and distributed environments, but I have not put that knowledge to use more recently; so it was good refresher from that point of view as well. From Yuck to completely Wow-ed is how I will like to describe my respect for Go within three days. I knew nothing about GO before the course."
Geoff Clitheroe (@gclitheroe)
"Your training is awesome! Myself and three colleagues recently caught variations of the training at GopherCon and OSCON. We all thought the Bootcamp was the best thing at any of these conferences (and I went to both). Awesome work to Bill for presenting and anyone involved in developing the training. I really liked the structure, emphasis on deeper understanding, me doing a small number of examples to emphasize this, and general content. Night and day to other training which is to often just watching someone else live code. Great work."
ACL Services (@ACLServices)
"I'd just like to thank you again for just a phenomenal training session. The feedback from everyone was overwhelmingly positive. You probably could tell first hand that there were skeptics at first, but you've turned many into golang converts and we are really excited in growing golang adoption internally."
Joshua Shuster (@naysaier)
"I would consider Ardan Studio's 3 day course to be invaluable. Bill and his staff, being some of the foremost authorities in the Go language, were able to make many of the complex go topics understandable. Covering everything from memory management, all the way up to building concurrency programs and web API's. It has given me the knowledge to write idiomatic Go, and make the best use of its features. I would highly their courses to anyone new to Go, or to anyone wanting to widen their existing knowledge."
Neeru Dwivedi
"I attended the one day workshop by Bill Kennedy from Ardan Labs. I was in for a surprise as before the workshop I was concerned whether I would understand concepts and whether I would be able to follow along. Bill has this wonderful way of explaining concepts and his knowledge on the concepts is so good that, I didn't feel that I was learning something new & complicated. The Go Workshop got me started on the Go language. This workshop is perfect for beginners and anyone who wants to learn more about Go. I highly recommend this."
Todd Rafferty (@webrat)
"I highly recommend William Kennedy / Ardan Lab for Go Training. William is extremely passionate about the Go language and his energy feeds into his training. Very professional, very informative. My favorite section of his training, if I had to pick, was the segment on MultiWriters. I highly recommend a 3 day course, over a 2 day course. Even after the classes were over, William was always responsive with additional questions via various social media channels."
Georgi Knox (@GeorgiCodes)
"The Intro to Go Workshop enabled me to come into class with very little knowledge of Go and leave having a firm grasp of the key concepts of the language. Each topic was followed up with hands-on coding problems which helped to solidify what I was learning. My teacher Bill was not only approachable, but very excited about the language and his enthusiasm was contagious. I enjoyed that we talked about some of the lower level implementation details of Go which was something that I had found lacking from some books on the language. Overall I would highly recommend this workshop to anyone looking to learn Go quickly and effectively."
