Sage Mountain Senior Living has 56 state citations (31 serious, 25 minor) and 34 verified complaints since 2021 across 85 inspections. The most recent verified complaint, closed in December 2025, documents staff failing to notify a resident's authorized representatives of 3 falls, the last on November 12, 2025. A 2025 investigation found that staff could not assist a resident to the bathroom because no Hoyer lift was available and the resident could not be manually transferred. A 2022 investigation found a resident experienced 4 falls, only 2 of which were reported to their physician, and that a 24-pound weight loss over 2.5 months also went unreported to the physician. Staffing complaints from 2023 and 2024 document 1 resident waiting over 1 hour for morning assistance out of bed and medication delays of up to 3 hours for multiple residents. In late 2024, following a management transition to a new company, a complaint found a resident's monthly care cost increased from $3,100 to $6,000 without adequate written notice.
