I’m Sheriff Shahen
Like you, there was a time I had no idea what I was actually doing wrong. I was making the dials, running the sequences, showing up every day, and still missing quota. I was working hard enough. I just didn't have the system that made it stick.
Nobody handed me one either.
I started in straight-up telemarketing, no polished onboarding, no playbook. Just a phone, a list, and pressure to perform. Over the next decade, I figured it out through 100,000+ real cold calls across B2C and B2B, and eventually worked my way up to AE at the fastest-growing SaaS company in the world at the time.
What I never had, until I built it myself, was a clear, repeatable system that worked even on bad days.
SDRing 101 is that system.
It's a decade of real experience condensed into exactly what survives real calls, real pressure, and real quota. My hope is that it gives you in weeks what took me years to figure out.
To your success,
Sheriff Shahen
