About MOUNTAIN GROUP LLC

Filed under sleep medicine, MOUNTAIN GROUP LLC is listed in Duarte, California, the United States. Address details come from the public listing: 931 Buena Vista St Suite 103. Its listed ZIP code is 91010.

The entry has no training, certification or language data, so those details are simply not shown. The listing cites npiregistry.cms.hhs.gov as its source.

Before booking, ask whether a referral or doctor's letter is needed, because requirements differ between practices and how a visit is funded. Confirm how payment works — up front, on the day, or billed afterwards — and whether insurance plans can be billed directly. Find out whether the first assessment leads to a home sleep test or an in-lab overnight study, and how long results take. Ask what to bring: a medication list, any referral letter, a sleep diary, and results from earlier studies. If you are travelling from another town, confirm parking, public transport and the exact entrance before the day. Find out whether the practice runs a structured sleep program and how many sessions it involves. Ask whether appointment confirmations and any forms can be sent before the visit. Confirm fees, availability and location directly with the practice, as directory listings are not updated in real time.
