Dr. Heather Larkin, Ed.D., LMHC, MGCP, MPM, AIMC
Mastermind Behind the ALL IN ECOSYSTEM. Architect of the ALL IN MINDSET™, Licensed Mental Health Clinician. Mental Performance Clinician. Author. Speaker/Trainer.
Dr. Heather Larkin doesn't just teach mindset — she engineers it under pressure.
With 30 years in mental health and performance psychology, she is the clinician athletes call when talent isn't the problem — but the mind is. The overthinking. The fear of failure. The perfectionism. The spiral after the mistake. She works where pressure lives.
She is the creator of The ALL IN Mindset™, a five-pillar performance framework built on Awareness, Letting Go of Limitations, Locking In, Intrinsic Confidence, and a relentless Next Play Mentality. It's not hype. It's mental conditioning designed for real competition and real life.
Dr. Larkin is the author of The ALL IN Mindset™: How to Fumble, Fail, and Still Come Out on Top — a powerful blueprint for building resilience through adversity — and The Car Ride Chronicles: How to Avoid Those Dreaded Car Rides Home, a straight-talk guide helping sports parents support their athletes without sabotaging confidence.
She is also the creator of The ALL IN EDGE™ App, a daily mental performance training platform for athletes who want consistency under pressure, and The ALL IN RECRUIT™ App, designed to give athletes and families a smarter, more strategic edge in the college recruiting process.
Dr. Larkin's creativity and passion is delivered in each of her proprietary trainings: The ALL IN Mindset™ specific to any sport, The Hero Within, a social-emotional learning workshop for youth athletes, The Car Ride Chronicles for sports parents, and Beyond the Xs and Os for coaches, The ALL IN Leader for team captains.
Based in Massachusetts, she leads ALL IN Counseling & Mental Performance Coaching, LLC, where therapy meets performance training and resilience becomes a lifestyle. Her ecosystem spans athletes, parents, coaches, and organizations committed to building mentally strong cultures from youth sports through the professional ranks.
She is direct. Strategic. Grounded in clinical science. And unapologetically committed to excellence.
Her mission is simple:
Condition competitors to think clearly, respond with intention, and execute decisively — when the stakes are highest.
Because being ALL IN isn't branding.
It's a standard.














What Guides Our Practice?
At ALL IN, we don't operate off trends, hype, or surface-level motivation. We operate off standards. These values shape every session, every program, every partnership.
Excellence Is Expected
We train the mind with the same intensity athletes train their bodies. Preparation eliminates panic. Discipline builds confidence. Showing up halfway is not our model.
Accountability Over Excuses
We don't blame circumstances. We take ownership. Growth begins when responsibility replaces rationalization. Control your effort. Control your focus. Control your response.
Pressure Is a Privilege
Pressure means the moment matters. We don't teach people to avoid it — we teach them to regulate it, harness it, and perform inside it.
Response Is Power
You cannot always control what happens. You can always control how you respond. We build emotional regulation and cognitive control so our clients respond with clarity instead of reacting with chaos.
Mental Health and Performance Go Together
Resilience is not denial. It is awareness plus strategy. We integrate clinical depth with performance training because emotional wellness fuels consistent execution.
Confidence Is Built, Not Borrowed
True confidence is earned through preparation, self-awareness, and repeated recovery. It does not rely on applause, rankings, or scoreboards.
Growth Requires Discomfort
Avoiding discomfort keeps you stagnant. Leaning into it builds capacity. Mistakes are not identity statements — they are data. We teach recovery as a skill.
Confidentiality Is Sacred
Trust is non-negotiable. Whether in therapy, performance coaching, or team consultation, we protect privacy with clinical integrity and professional rigor. Growth only happens where safety exists.
Collaboration Creates Results
We work alongside athletes, parents, coaches, and organizations — not above them. Sustainable performance culture is built through aligned communication, shared responsibility, and unified standards.
The Next Play Always Exists
Mistakes happen. Slumps happen. Life happens. The question is not whether you fall — it's how quickly and intentionally you reset.
