Why seasoned practitioners choose Sigma Therapies

We are a clinician-led provider that trusts you to practise independently—no micromanagement, no unnecessary red tape. You manage your own full-time caseload, shape interventions the way you know works best, and decide how you allocate your therapy, report-writing and travel time. And because commitment deserves recognition, our transparent bonus system pays you extra each quarter when you choose to take on additional billable hours. As our service expands, you’ll also have a clear pathway into senior, lead and management positions, with the chance to help shape clinical governance and mentor the next generation of practitioners.
