Treatment Approach

Dr. Fortino believes medication is one tool among many, not the whole plan. He and his clinical team start GLP-1 medications at a low dose and adjust gradually to find the lowest effective dose, based on each patient's tolerance and progress. Throughout treatment, they manage side effects proactively, protect lean muscle and plan for maintenance from the first visit. Patients also get a clear exit strategy if they want to come off medication.

Every plan is tailored to the patient and guided by in-person evaluations, body composition results and lab work when needed. Whether a patient wants to lose fat, gain strength and energy or improve metabolic health, Dr. Fortino offers experienced, evidence-based and nonjudgmental care built around a long-term doctor-patient relationship.
