Certified Scrum Professional® - Product Owner

The course covered areas that may be weak or could benefit from challenging the status quo in my area. This was very welcome.

Excellent training ! Exquisite professional trainer ! Presentations held, materials and tools are on the highest professional note!

Excellent training. Knowledge. Flexible. I am looking forward to attending another course led by Arlen and Grow-Lean.

Arlen was an excellent instructor. Ver good class and the time went by fast, which is attributed to Arlen.

This was one of the best training courses I have ever taken. Arlen is an expert and an engaging and experienced instructor. I look forward to taking future courses with Grow-Lean and Arlen.

Arlen looks at the whole picture of product, and provides great frameworks for discovery analysis. And he is, himself, continuously reformulating and expanding his perspective on the industry. He has a deeply informed view of the space and conveys it with a wonderful mix of passion and and openness.

Arlen is a great trainer, who provides very informative material, and makes it enjoyable/fun at the same time.

Well thought-out and great delivery, with in-depth examples.

Nothing but great things, lot of new concepts and amazing conversation!

Fantastic!
