Need an advice

Hello, I’m looking for a professional firm that can do PCB assembly and box construction including potting. The ability to implement engineering and testing is crucial. I found https://asselems.com/en/medical-electronics-manufacturing on the internet, and their website seemed to be trustworthy. Have any of you heard of this company before? An unbiased comment from someone who has done it would be greatly appreciated. Please let me know what you have to say.
