# Free 15-Minute Initial Consultation with Carlos Reyes

> Tell me what you’re working on — a class, a project, a career change, a skill you’re leveling up. I’ll tell you honestly whether I’m the right mentor for it and what a plan would look like. If I’m not the right fit, I’ll tell you straight and point you somewhere better. No pitch, no obligation. Mentoring sessions are $99/hour and are booked separately if we decide to proceed. Did you find me through a tutoring platform such as Crimson Education or Wyzant? I only take students booked independently. If you found me through a tutoring marketplace, please book through those websites instead.
