About

You hired an agency to grow your brand. The strategy looked solid on the pitch deck. But once you were onboarded, things started to feel… off. Your account got handed to someone junior. Decisions were made without really understanding your margins or your data. And when results didn't come, the reporting got busier, but the clarity didn't improve. It's a pattern that's frustratingly common in this industry. Most agencies are optimized for scale, not outcomes. And when you're a founder who lives and breathes your numbers, that gap is hard to ignore. I started REACH because I've been on both sides of the table, scaling brands like Fanatics and Beauty Bay as an operator, and working closely with agencies as a decision-maker. I understand what good looks like, and I built REACH around that standard. Here's what working with me looks like: → You work directly with me. No handoffs to junior team members or overseas contractors. → Every decision is grounded in your data: margins, CAC, LTV, not just ROAS. → Strategy that's built for profitable growth, not activity metrics. My clients' results speak for themselves: 📈 +182% YoY Shopify sales 📧 +243% YoY email revenue 🎯 +62% YoY conversion rate improvement REACH works best for founder-led Shopify brands doing $15K–$150K/month who want a senior operator in their corner, not another account manager learning on their budget. If that sounds like you, the first step isn't a sales call. It's a free Growth & Revenue Audit, an honest look at what's working, what's broken, and exactly where your next $50K in revenue is hiding. 👉 DM me "Audit" or hit the link below to claim yours.

Experience

  • Founder & CEO at REACH E-Commerce Consulting
    Mar 2022 - Present · 4 yrs 4 mos

    I help brands turn underperforming sales channels into scalable profit. Built and scaled a full-service agency delivering Shopify sales growth of +182% YoY, conversion rate improvements of +62% YoY, and email revenue increases of +243% YoY for clients across FMCG, sports, beauty & more. Managed $4M+ in ad spend, generating $11M+ in online sales and $2.2M+ in email revenue. From launching high-converting Shopify/Wix stores to managing end-to-end eCommerce ops (paid media, email/SMS marketing, CRO, UGC, influencers/affiliates and analytics), I combine strategy, execution, and measurable results to drive growth.

  • Founder (Sold) at RECOSIVITY
    Mar 2022 - Sep 2025 · 3 yrs 7 mos

    Built and scaled a direct-to-consumer Shopify brand from the ground up: sustainable athleisure, designed and manufactured in the USA. Took full ownership of every layer of the business: brand identity, product development, Shopify store build, paid media, email marketing, influencer strategy, and operations. No agency. No playbook. Just hands-on execution from zero to exit. Successfully sold the business and exited to focus exclusively on REACH E-Commerce Consulting. RECOSIVITY is where the strategy became personal. Running my own brand by managing real ad spend, real margins, and real customer relationships gave me a ground-level perspective that most consultants and agency founders simply don't have. It's the reason I can sit across from a Shopify founder and understand not just the metrics, but the pressure they feel.
