‘Suvi Knaapila is by far the best HR legal advisor I’ve worked with in 15 years. She always makes time for us, covers different scenarios and approaches, and has taken extra time to understand our working culture and how her HR input and counsel aligns with that. She helped with everything from contracts, to layoffs, furloughs, negotiations, and other HR scenarios. We’ve also talked about different growth scenarios and how decisions I make now may impact us in the future. I really feel we’d be lost with Suvi’s excellent direction.’

‘Top team when facing complicated cases which need out-of-the-box thinking.’

‘Best overall knowledge of employment legislation among Finnish firms. Wide network of contacts.’

‘I truly enjoy working with Dittmar & Indrenius. I’ve worked with them on contracts and HR- their responses are always swift, and even though we are perhaps on the smaller side in terms of workload- I am always made to feel like a priority. Their attention to detail, and their forward thinking is highly valued. They look to prevent and solve future problems as well, not just whatever I’ve called them for.’

‘Petteri Uoti is by far a leading star in Employment issues in Finland. He has outstanding knowledge of Employment legislation and problem solving. He is also very good at presenting his views. Seppo Havia also has top notch capabilities. Mika Kärkkäinen is a rising star with extremely good knowledge of Employment issues.’

‘I think that Suvi Knaappila is just superb in building a trusting relationship. Supporting me through a though process in a very professional and friendly way. She is always available with very short notice.’

‘True professional team that knows how to speak to us in an understandable language. Not using too many difficult terms and expression. Very friendly and understanding. Supporting in a professional way.’

‘Petteri Uoti – strong knowledge base and talent to open the issues at hand. Seppo Havia – marvellous litigator keen on finding new approaches. Suvi Knaapila –  hard working solid, convincing top performer.’
