Built by a clinician-engineer.
Not by a marketing agency.
SJ iTech is a Sydney digital agency that builds the full growth system for owner-operated dental practices in the Hills District and Northern suburbs. Founded by Dr. Peyman Obeidy after 15+ years building AI and automation systems for healthcare.
Dr. Peyman Obeidy
Founder & CTO · SJ iTech Pty Ltd
Peyman spent 15+ years building AI and automation systems for healthcare — including senior engineering work at Siemens Healthineers on medical imaging AI (DICOM/PACS, deep-learning segmentation, clinical workflow automation), and postdoctoral research linked to Harvard Medical School. He holds a PhD in Medical Science from the University of Sydney.
SJ iTech exists because Australian dental practices kept asking him the same question: “How do we use AI to grow without losing the clinical feel?”The answer wasn’t another SEO agency. It was a full growth system: search visibility, AI receptionist, automated follow-up, measured weekly. PhD-led. Sydney-built.

Four operating principles.
Every engagement runs against these. They’re what stops us from becoming a generic SEO shop.
- 01
We sell the system, not the service.
Most agencies sell SEO. We sell Found → Chosen → Booked → Followed. SEO without conversion is wasted clicks. Conversion without follow-up is wasted leads. The system closes every leak.
- 02
Sydney-owned. Hills + North only.
We don’t take dental practices outside the Hills District and Northern suburbs. Local market knowledge — competitor mapping, suburb-by-suburb keyword intent — is the wedge. We can’t do that nationally.
- 03
PhD-led, not pitched.
Strategy work runs through Dr. Peyman directly. The same person who shipped imaging-AI systems at Siemens designs your growth system. No three-layer agency hierarchy.
- 04
Guaranteed or we don’t deserve to be paid.
90-day ranking improvement guarantee on every engagement. If you don’t see measurable ranking progress inside 90 days, you don’t pay for month four. Simple.
