Celena was very helpful, professional and thorough. She came to run diagnostics for my classic car and she made sure to check every nook and cranny while explaining everything in a comprehensive way. She has an eye for detail and knows her stuff.

About Celena

The Mechanic Who Shows Up

ASE Certified. 15+ Years. 1,000+ Customers.

Celena started Tech On The Way as a pilot program in New Jersey in 2016. By 2019 she had proven the model: bring dealership-level diagnostics and repair directly to the customer, wherever their vehicle is. In 2021, she brought it to Atlanta.

Since then, she has served over 1,000 customers across 10 Metro Atlanta counties. Her ASE certification is earned, not bought. Every technician on the team meets ASE, OSHA, DOT, and manufacturer standards. Every repair comes with a 12-month, 12,000-mile warranty.

What makes Celena different isn't just that she comes to you. It's that she explains what she's finding as she works, so you understand your vehicle. Multiple reviewers note her thoroughness, her patience, and the fact that she never upsells. One customer said she rescued them from a breakdown 550 miles from home on a weekend evening when no shops were open.
