Certifications that actually helped your career?

Curious as to everyone's experience with various supply chain or business in general certifications that have helped your career advancement.

I see a pretty mixed bag of successful people in the industry, some with certifications and some without. Personally I do not have any certifications and I am not sure it has hindered me to to this point (Sr Buyer role) but I am curious if there is anything worthwhile I should be pursuing.

Thanks for any input.
