www.kashrut.org are they orthodox
Yes, they are definitely Orthodox and highly recommended regarding their expertise in kashrut and the US hechsherim. It is Rav Abadi and his sons. Rav Abadi was for a time the posek (Rabbi who "paskens" halachic decisions) of Lakewood - a large, well-known Torah-observant community in NJ. It is a very helpful website from my experience.
