Tableau Visionaries & Alteryx Aces ready to teach

Andy Kriebel

Andy, a member of the Tableau Zen Master Hall of Fame, started using Tableau in 2007 when he was desperate for help to quickly create dashboards using SSAS cubes. Since then, it’s been Andy’s personal mission to help as many people as possible “see and understand” their data with Tableau, which is the focus of his role as Head Coach at The Information Lab’s Data School. Data is knowledge, but Andy believes that seeing data is insight.

In August 2009 he launched vizwiz.com, which provides examples of data visualization best practices, methods for improving existing work, and tips and tricks with Tableau Software. He writes two weekly series: Makeover Monday and Tableau Tip Tuesday. Andy also founded the weekly Tableau Community project Workout Wednesday. He also writes on datavizdoneright.com along with Coach Carl, a site created to highlight data visualisation best practices.

Carl Allchin

After a one day Tableau training course from The Information Lab several years ago, Carl became a Tableau addict and decided to make it his full time job. Carl joined The Information Lab in September 2014.

Carl’s experience focuses on Operational Improvement, Customer Experience measurement and Propositional development.

In his own time, Carl runs the blog Data Jedi Ninja that focuses on Tableau tips, tricks and visualisation experimentation. This allows him to visualise sporting data, especially basketball, and have a global discussion about what he finds along the way.

Carl is a Tableau Desktop Certified Trainer, Tableau Server Qualified Associate, and an Alteryx Certified Trainer.

Martin Pohlers

Martin has always had a passion for numbers and analytics. After his dual business studies in Nuremberg and a master's degree in applied statistics in Oxford, he finally moved to Hamburg for his professional career. Here he discovered his passion for Tableau and Alteryx and has been a trainer and consultant at TIL since 2015. He enjoys spending his free time playing tennis, bowling and skat or discovering distant countries and cultures.

Martin is a Tableau Desktop, Prep and Server certified trainer and has the Desktop and Server Certified Professional certifications. For Alteryx he holds the Alteryx Partner Technical, Server Technical and Server Implementation certification.

Benedetta Tagliaferri

Benedetta’s journey starts with an undergraduate degree in Business Administration in Florence, an Erasmus in London and a master's degree in Finance and Markets. She moved to London to develop her tech skills and got enthusiastic about data. She was part of the second intake of the Data School UK, learning to use Tableau, Alteryx, SQL & project management skills.

She has been a Tableau & Alteryx consultant for more than 4 years, helping organisations with their data every day. Now she is responsible for the L&D of the Data School, designing and implementing strategies for mentorship, mental health and career development of the consultants.

She loves to find opportunities with charities and connect them with volunteers that want to use tech skills for initiatives that have a social impact on the world. She created TIL+, the probono arm of the Information Lab, which got recognised twice by Tableau with the Data for Good award. In 2022, she won the Data for Good Champion award from Data IQ.

Jenny Martin

Jenny joined the Data School in April 2019, hoping to develop a specialism and expertise in data. She found her passion in all things Data Prep, whether that be through Alteryx or Tableau Prep. From 2020, Jenny got involved with helping to run the Tableau Community project Preppin' Data - giving the community weekly data prep challenges to complete in their tool of choice. She's also a co-lead for the Tableau Prep User Group and a Tableau Social Ambassador. At one point, Jenny challenged herself to complete all the available Alteryx Weekly Challenges (233 in a year) and she also holds the rare Alteryx Expert Certification.

After joining the Core team at the Information Lab in August 2021, Jenny worked with a variety of clients, but also had the opportunity to start teaching at the Data School. She finds nothing so rewarding as a day spent in the classroom.

Outside the data world, Jenny loves spending time with her mischievous cat Pyrrha and dabbles in a variety of nerdy hobbies, from Pokémon to roller skating along the seafront

Jonathan teaches Tableau Server and IT fundamentals to all of The Data School cohorts.

Lorna Brown

Lorna started her data journey during her masters degree in 2014. Due to her love of sports and data, she became part of the second cohort of The Data School UK.

Once Lorna had finished The Data School, she went on to speak at many Tableau Conferences, which involved Speed Tipping. She did this with Ann Jackson, Head Coach of Data School New York.

Now Lorna co-lead the community initiative Workout Wednesday with several others and also co-leads the North West UK Tableau User Group. She is also the author of Tableau Desktop Cookbook (2021). Lorna is one of our Tableau Visionaries and Tableau Public Ambassadors.

Robbin Vernooij

Collecting, processing and making sense out of data have been at the centre point of Robbin’s interest throughout his journey from the Netherlands to Australia and now the UK.

During his BSc, MSc studies in Chemistry and PhD in chemotherapeutics he soon realised that breaking down, translating and presenting complex data sets for everyone to understand is one of the things he enjoys doing most.

Robbin joined the Data School in Feb 2018 and being exposed to Alteryx and Tableau opened up a whole new world of streamlined data processing and amazing avenues to tell your story using data.

He has been consulting, training and coaching clients and data schoolers on all Desktop and Server aspects of Tableau and Alteryx ever since.
