"Even though I already had experience using Power BI, the course content was able to identify skills and techniques that I have not used previously. A great trainer, who really broke down Dax into a more understandable concept."

Gabriel Averia

Frontline Ltd

"A great trainer who made everyone feel at ease & was extremely knowledgeable. Even though the subject was something that I thought I would struggled with, the training was broken down into small enough sections that we could all follow easily."

Stephen Catlow


"Great content. Great trainer. Thoroughly enjoyed how trainer engaged with us. Exercises helped cement course knowledge."

Hazem Hawwash

RPC Group plc

"The course was great! Learned so much and even gave me new ideas/knowledge on how to startup my project. The trainer is brilliant with the way he made the lessons so easy to understand (despite the information overload). Great job and thanks again! "

Ramon Dimaano

Waltham Forest Council

"To my surprise the online version worked really well, I wasn't sure if it would as I much prefer at site training. We had a really good, friendly and engaged trainer. "

Joyce Fajemirokun

Girls' Day School Trust

"Our trainer was enthusiastic and very helpful. He took the time to go back, where people had missed things and helped with any questions we had to do with our own work, not focused on the course. He allowed us to tailor the course as we wanted and choose our own path with what he demonstrated. I chose Wise Owl due to its reviews, its price was competitive and covered everything I wanted in a convenient manner. I would ask to go on another Wise Owl course in the future."

James Hinkley

Homes England

"Excellent training, well paced and engaging delivery of the training."

Andy Dowling

Parliamentary and Health Service Ombudsman

"The trainer was very helpful, friendly and open to questions, which made the sessions a lot more enjoyable and engaging. The pace of the sessions was just right (not too fast but not too slow) and the trainer being able to view our remote desktops was a very useful feature, as it meant he could help us over any stumbling blocks. We covered an impressive range of content, much of which should be useful for my work. I also appreciated the care taken in ensuring the course ran smoothly, i.e. the pre-course checks and the provision of accompanying materials well in advance of the sessions. I had seen examples of what others have done with Power BI and wished to be able to produce similar myself."

Chris BurridgeBarney

Devon County Council

"Excellent course, very informative and run smoothly. The trainer was interesting and engaging. Hope I end up needing some more training soon! My boss loves you guys."

Jack Tildsley

Derby and Burton Hospitals NHS FT

"An amazing trainer, very knowledgeable and professional (he is funny as well). Overall Wise Owl have delivered the best training I've ever had. My manager recommended Wise Owl in the first place. After my SQL and Power BI training I know why he speaks so highly of you guys. We are very happy with the trainings provided. Looking forward to coming back. Thank you all!"

Cristina Schmidt

Wiggin LLP

"Really enjoyed the course, thank you all. Brilliant trainer, very engaging, gave clear explanations and made the course informative and enjoyable. Particularly liked the course format (following along with the trainer's screen) - when learning remotely it's difficult at times to keep alert and I think that this was a great way to keep us engaged throughout - I felt I learnt more this way too."

Andrea Shaw


"Clear content. Excellent pace."

Peter Worthington

Waltham Forest Council

"Great trainer. Very patient and knowledgeable. Really enjoyed the format. Online works better than classroom. Work college recommended you."

Bradley Jemmett-Smith

Retail Insight

"The course was great and very beneficial. The content was good and the trainer was great. The layout of the room including refreshments was very thoughtful."

Ahbab Miah

London Borough of Tower Hamlets

"Really enjoyed this course. Thought the training was really practical and our trainer was fantastic. Really engaging and made everything very easy to understand. Came away with loads of ideas for my business. Second course I have attended with you. Really impressed by your trainers and how much care and attention you take to delivery and course materials A++++"

Dan Mullender

Parliamentary and Health Service Ombudsman

"I thought the course was really well organised and it was clear that your team had thought through the online element. I think it had the right tone and balance between examples and hands on practice. Very much enjoyed and thought the advanced elements covered i.e. beyond XLOOKUP were explained well and will be hopefully useful going forward."

Mathew Pinkney


"I really enjoyed the course. I'd previously had a quick insight into Power BI and it looked very complicated but the trainer made it look easy & relatively straightforward. Course was very organised and the manual and notepad were very useful – I’ll certainly be using them in the future."

Emma Russell

Torus (Housing Trust)

"Excellent course well presented. Gave a concise understanding of what DAX can and can't do and how to make sense of previously unexpected outcomes from formulas. Training recommended by a colleague."

Jamie Rowley-Clarke

Cross Keys Homes

"Superb course with a great and thorough trainer. Really enjoyable."

David Cohen

UP Global Sourcing (UK) Ltd

"Really appreciate the accompanying manual for future reference."
