Every state is required by law to have an elder care ombudsman program.
You can find out all that information, and more, by visiting their website and calling their office.
Here is Maryland's:

The Maryland Long-Term Care Ombudsman Program advocates for the health, safety, well-being, and rights of residents in assisted living and nursing homes. Ombudsmen work at the direction of the resident and only take action with the resident's [or family's] consent.
Ombudsman services are resident-directed, confidential and provided free of charge.
The Maryland Long-Term Care Ombudsman Program also improves the quality of care and increases the quality of life for over 54,000 Maryland residents living in long-term care by advocating for laws, regulations and policies that benefit residents.
Ombudsmen visit Maryland’s 1,850 assisted living and nursing homes nearly 7,000 times each year, resolving approximately 3,300 complaints from residents.
