Healthcare & medicalHIPAA-aware build

Dental practices

A new patient searching at nine PM is deciding in twelve seconds whether to call you tomorrow or the practice three blocks east. The site that loads cleanly, books online, and shows the doctor's face is the one that wins.

  • HIPAA-aware intake forms with proper consent capture
  • Provider bios with Person + MedicalBusiness schema markup
  • Mobile-first speed — under 2.5 seconds on a phone

Process

How we work.

Methodical process ensures no stone left unturned. Cutting corners early shows up later, so we don't.
STAGE 01
DISCOVERY

Outreach and initial consultation.

A conversation before a contract. We listen to the problem, the constraints, and the non-negotiables — and if we are not the right firm to solve it, we say so and point you at someone who is. If we are, we follow up with a fixed-scope proposal and contract for your review before any work begins.

STAGE 02
RESEARCH

Research on brand, problem, and positioning.

Before we write code, we understand the work. We study the business, the users, and whatever system already exists — and produce a written brief stating what the first build must prove and what it will deliberately leave out.

STAGE 03
DELIVERY

Quick turnaround.

We ship a working product fast — days, sometimes same day, not quarters. Revisions are unlimited, and come just as quick.

STAGE 04
MAINTENANCE

Maintenance mode.

Once all parties are satisfied with the product, an engineer stays on retainer. Update requests implemented, bugs fixed, capabilities extended as the business asks, for as long as the system runs.

Pricing (modular)

Pick what you need. Skip what you don't.

Monthly retainers, no upfront build fee. Hosting, infrastructure, and third-party tools absorbed. Start at $200/mo, add only what you'll use. Items marked Scoped get a flat quote after a 30-minute call; Pass-through items bill at vendor cost with no markup.
