"I can't keep doing this all by myself."

If you've said that lately, you're not behind and you're not doing anything wrong. You're simply wearing every hat in your business.

Your inbox follows you home every evening.
You're holding the whole business in your head.
The small tasks keep crowding out the work you actually love.
You're overwhelmed, and not sure where to even begin.
how I work

The LOOP Method

One of the biggest misconceptions about AI is that it takes the human side out of your business. It doesn't. Done thoughtfully, it gives you more room for it.

L

Locate

We look at your week together and find the tasks quietly taking up your time.

At Cornerstone: I started with my own week. Email, onboarding and content were taking hours I didn't have.
O

Optimize

We decide what AI handles, what it helps with, and what stays with you. Nothing important happens without your say.

At Cornerstone: AI drafts. I review and approve. Every time.
O

Operate

I build, test and document each system, with simple steps you can follow.

At Cornerstone: my inbox, proposals, invoices and social posts now run steadily in the background.
P

Partner

I stay close as your human in the loop, so things keep running smoothly as you grow.

At Cornerstone: a daily check tells me right away if anything needs attention.

What's running in my business right now.

Before I build anything for you, I build it for Cornerstone first.

Knowledge base

A business brain that knows Cornerstone.

Everything about how Cornerstone runs lives in one organized place: my services, my voice, my guardrails, and a team of specialist assistants that work from it. It's connected to my Google Drive, so it always works from the latest version.

What it does for me: Every assistant, from my inbox to my social posts, works from the same source of truth, so everything sounds like me.
AI inbox assistant

An inbox that sorts itself, twice a day.

Every morning and evening, my inbox is sorted into folders, replies are drafted in my voice and saved for my review, and anything sensitive is flagged for me personally. Nothing is ever sent without me.

What it does for me: Replies are drafted twice a day, so no email waits more than 24 hours for a response.
Client onboarding

From signed agreement to ready to start.

The moment an agreement is signed, the client folder, time tracker, QuickBooks customer and first invoice are all set up, and a welcome email is drafted and waiting for my approval.

What it does for me: About ten setup steps now happen on their own. I just review and send.

Client stories are coming soon. Would you like to be one of the first? Let's talk.

why Cornerstone

I know what it feels like to wear every hat.

For more than 25 years I've worked behind the scenes in the trades, oil and gas, healthcare, nonprofit, ministry and small business. When I started my own business, I felt the same overwhelm my clients describe. Cornerstone is my answer to it: a trusted partner who brings organization, consistency and peace of mind, not just someone checking tasks off a list.
