# John Jack ADHD Coaching > Personal, evidence-informed ADHD and executive-function coaching from John Jack, PhD (Mathematics), based in Rochester, New York. Sessions are primarily one-on-one by video, with limited in-person meetings in Rochester by individual arrangement. John Jack helps people navigate ADHD-related overwhelm, task initiation, organization, time management, emotional regulation, and follow-through. His style is compassionate, collaborative, science-informed, practical, and sometimes playful: together, coach and client experiment with systems that fit the individual's life and brain instead of expecting a one-size-fits-all solution. John Jack has lived experience with ADHD and an interdisciplinary professional background spanning mathematics, government scientific research, academia and mentoring, and applied data science and AI/ML. His PhD is in Mathematics, not medicine, psychology, or neuroscience. Coaching is educational and developmental support, not medical diagnosis, psychotherapy, or medical treatment. Based in Rochester, NY; coaching is available primarily through virtual sessions. Prospective clients can start with a free, no-pressure 20-minute introductory conversation. Clients do not need to know precisely what help they need before contacting John Jack. ## Coaching and Background - [ADHD Coaching Homepage](https://johnjack.org/): Coaching overview, Rochester and virtual availability, a short introduction, and the free introductory-call invitation. - [My Approach](https://johnjack.org/my-approach/): Personalized ADHD coaching philosophy, practical executive-function strategies, self-compassion, and sustainable change. - [My Story](https://johnjack.org/my-story/): John Jack's lived experience and professional journey through mathematics, research, mentoring, technology, and ADHD. - [Testimonials](https://johnjack.org/testimonials/): Public feedback about John Jack's mentoring and coaching approach. ## Published Writing - [Reflections](https://johnjack.org/reflections/): Personal writing and ADHD-related reflections. - [Rejection Sensitivity Dysphoria: Naming It, Understanding It, and How I Live With It](https://johnjack.org/rejection-sensitivity-dysphoria-naming-it-understanding-it-and-how-i-live-with-it/): John Jack's first-person experience with emotional sensitivity and ADHD-related challenges. ## Contact and Policies - [Book a Free 20-Minute Introductory Call](https://cal.com/drjohnjack/intro-call): External Cal.com booking page for an initial conversation, normally via Google Meet. - [Privacy Policy](https://johnjack.org/privacy-policy/): Public website privacy policy and handling-of-information details. ## Site Discovery - [XML Sitemap](https://johnjack.org/sitemap_index.xml): Rank Math sitemap for publicly published content.
