About the practice
Marsh Clinical Nutrition
Marsh Clinical Nutrition is a Chicago-based private practice led by Elena Marsh, RDN, focused on complex gastrointestinal conditions that rarely resolve in a single short appointment.
Elena works with adults managing SIBO, IBS, food sensitivities, and post-treatment GI recovery — combining lab review, symptom mapping, and phased protocol design so clients know what to do between visits, not just what to avoid.
Sessions are available in River North and via secure telehealth throughout Illinois. The practice integrates with Practice Better for scheduling and uses a structured three-phase care model built for continuity, not one-page handouts.
I spent three years in clinical research before moving to private practice, specifically because patients with complex GI needs were not getting the time they needed. Fifteen-minute consults could list restrictions, but they could not hold the full picture — breath test results, medication timing, reintroduction schedules, and the anxiety that builds when every meal feels like a gamble. I built Marsh Clinical Nutrition to provide the deep-dive support those patients were missing: enough continuity to run a real SIBO protocol, adjust when symptoms flare, and land in a maintenance plan that feels sustainable. That is the work I care about most.
