Pros
Modine is definitely one of the industry leaders in their field of heat management. They are technically very well-positioned to maintain that status with their testing capabilities, engineering resources, etc. They seem to promote from within quite well, which allows them to keep top talent for the long term. Good opportunities for training and traveling to manufacturing plants for career advancement.
Cons
Like many companies that think of themselves as industry leaders, I think Modine has a bit of a blind spot in terms of thinking their way is the right way. This may be changing, but there are a lot of long-time employees who have not worked anywhere but Modine and that seemed to set the tone for the corporate mindset and overly conservative corporate culture.
