Loyalty + culture is what holds a fast-scaling business together.- Your health changes your leadership. Garen’s heart transplant shifted him from “General Patton” to servant leadership.- Invest in marketing early. Shamrock spends 3 months marketing before opening new markets.- Best ROI today = Google Ads + LSAs + reviews. Traditional TV is dying, OTT is still hard to track.- Control your ecosystem. Shamrock runs marketing in-house, builds its own software, and trains its own people.- Reviews win trust. Thousands of local reviews (with photos and PM names) directly drive calls and sales.- AI is no longer optional. Shamrock’s Trussi.ai CRM + AI workflows save $150K/year and accelerate everything from content creation to call center operations.- Call center = conversion engine. Eight in-house reps, AI-integrated with Nextiva, ensure no lead is wasted.- Not all customers are good customers. Learn to qualify and walk away from tire-kickers.- Stay focused.
