Hi there, and thanks for considering to add your business to OSM!

Please note that OpenStreetMap is a public non-commercial geodatabase, so I'd recommend you to avoid using qualitative/"SEO" terms like "best", "fastest", "cheapest" etc.

That being said, I've added the clinic, which you can see here:
https://www.openstreetmap.org/node/13318742489

Next up, consider adding opening hours, payment types accepted, contact details and wheelchair accessibility of the clinic.

Best,
NLBRT
