“Do not withhold good from those to whom it is due, when it is in your power to do it.” — Proverbs 3:27

Dr. Sandy believes that life-saving bariatric surgery should be accessible, not gatekept by corporate greed. She recognized a critical flaw in the medical tourism industry: facilitators and "agencies" that mark up the cost of surgery by 20% to 40% just for acting as a middle-man. Dr. Sandy firmly stands against large corporations that treat patients as commodities. To achieve her vision of making transformations truly accessible, she pioneered a "No Agency" direct-to-patient model at Cornerstone Bariatrics.
