START SPEAKING WITH CONFIDENCE →"The structure of this course—short, focused, and easy to build into your workflow—was game-changing"
- Sam Saluja, CEO at Guardrail
Before the ISA, I was not being authentically myself during presentations, as I felt it was unprofessional. After the ISA, I learned to lean into authenticity and use frameworks around storytelling and voice tonality. Preston was absolutely masterful in his approach to teaching the course..... 10 out of 10!!!
ISA changed the way I think of myself as a presenter! Preston's course helped me to structure my thoughts, highlighted the necessity of clarity in what I am delivering: for myself, and consecutively, for my audience. The best part of the program is lots of practice! I highly recommend ISA if you're aiming to establish your "presence in the room", level up your sales game, are a new job hunt, or on a career advancement path. Thank you Preston and ISA!
The ISA gave me the confidence and frameworks to speak clearly in any situation. Preston's teaching style makes complex concepts simple and actionable.
My name is Neri Garcia. Before the ISA, I struggled with having too many filler, talking too fast, and ums, which made it hard to stay on topic. I love the sign post as it helped me stay on topic and answer questions correctly. Thank you Preston! This is an amazing class and I highly recommend it to anyone at any level in their career. I am looking forward to learning more techniques from Preston.
Preston -- thank you so much for this program! Hands down the best communication coach! I'm applying the frameworks in real time whenever I am on a teams meetings or giving a presentation. I have been reaping the benefits every single time!
This is you.
Struggling to articulate yourself clearly and concisely when you're on the spot...
- ❌ you feel too anxious to speak up in meetings.
- ❌ so when you do, you stutter, ramble, and miss your point.
- ❌ you live with heightened anxiety before and after you speak because you're so embarrassed by how you come across.
- ❌ you see others get selected for presentations and opportunities because they're more articulate.

Hey, I'm Jannis--a builder of community, teams, and now a startup. Before the ISA, I used to overthink everything I said--especially in interviews or leadership settings. After the ISA? I speak with clarity and confidence, thanks to frameworks that actually stick. Because of ISA, I've skipped straight to final interviews, nailed my 'tell me about yourself' pitch, and even landed a scholarship to a pre-accelerator. My startup is now one of the top ideas in the cohort--and I've built a team that believes in the vision. I've also seen huge shifts in everyday life. I improved communication at church, found an accountability partner in the ISA community, and now get told my leadership is 'clear, inspiring, and authentic.' Because a couple of months ago, I wouldn't have described myself that way. If you're on the fence, trust the nudge. ISA helped me find my voice--and I use it everywhere now!

What ISA Alumni Are Saying
Impromptu Speaking Academy is the single best investment I've made in my communication toolbox. It turns everyday speakers into strategic communicators. First, it teaches not just how to speak but why. Every lesson builds on a solid communication foundation, clear connection intent, and proven frameworks. Second, the course platform is easy to use and offers a ton of relevant content and opportunities to practice. Finally, the syllabus blends crisp theory with rapid-fire drills, so every concept is reinforced in a fun way and can be applied in real-life scenarios immediately. For example, while prepping for a high-stake meeting at work, I clearly mapped what I wanted the audience to know, feel and do. I also used a few frameworks strategically to facilitate the conversation. The leadership called it 'the most productive meeting I've seen in a while'. For professionals who want to replace rambling and confusion with effective and clear communication, this course is a decisive, results-driven investment.
As a Senior Product Manager in tech, clear communication is critical. I need to influence leadership and simplify complexity on the spot. Before the ISA, I struggled to reproduce good communication consistently. Under pressure, I would either over-explain or lose the core thread. I didn't have a reliable structure to organize my thoughts quickly, and practicing alone wasn't translating into real performance. After the ISA, something finally clicked. I now have repeatable frameworks that work in any situation: leadership updates, impromptu Q&A, presentations, even networking intros. I can structure a response in seconds, stay focused, and land the message with clarity. It's becoming muscle memory. What surprised me most was the speed of the progress. The community practice creates authentic pressure while still feeling safe and supportive, and you see yourself improve in real time. Preston has a rare skill: he can pinpoint the exact moment a message loses power and give feedback that is simple, tactical, and transformative. He is patient, encouraging, and truly invested in your success. I am genuinely grateful for the progress. I've taken other speaking courses, but this is the first one that combines live community reps and an app for daily practice, which is exactly what I needed to build a lasting habit and see results this fast
Taking Preston's ISA course has been very helpful for me. Before the ISA course, I struggled with speaking confidently on the spot, often not being clear and concise on what I was trying to say. However, taking the ISA course has truly helped me with my speaking abilities. The structured framework he provided gave me clear, actionable steps to organize my thoughts quickly and communicate effectively, even in high-pressure situations. I now feel much more confident when speaking impromptu and have noticed a significant improvement in my overall speaking skills. I'm incredibly grateful for Preston's course and the skills I've gained through it. I highly recommend it.
I had an excellent experience attending Preston's Impromptu Speakers Academy session. The way he used clear, practical examples and demonstrated communication strategies made the concepts easy to grasp and apply right away. I especially appreciated the balance between main sessions and breakout rooms, where we had the chance to practice and receive live feedback directly from Preston. His energy, positivity, and engaging tone created an atmosphere where participants felt encouraged and supported. The combination of structured frameworks, hands-on practice, and real-time coaching made the session highly impactful. I would recommend this program to anyone who wants to sharpen their impromptu speaking skills for both professional and personal settings.
I am a senior executive of a University Administration team. I am a believer of continuously upskilling and reskilling. As i was shopping around for courses on public speaking skills, happen to chance upon Preston's course. I was impressed by Preston's deliver and signed up for his online course. Even just attending his preliminary session, I took away more than I expected!
This is not just another training course. You will take away learnings for life. I was particularly impressed with Preston's personalized approach to help you grow in your specific needs. Highly recommend!
ISA has been very effective in helping me organize my thoughts and be articulated in speaking. I would like to mention that Preston uncovered the techniques one at a time and provided enough practice to make it our own. He then brought it all together in a cohesive manner that made absolute sense. I am excited to keep my journey of articulated speaking on using these techniques. All the best to Preston and all future cohorts.
I had the privilege of participating in Preston Chin's speaking course, and I can confidently say that it was a transformative experience. Having taken a few speaking courses in the past, what truly sets this course apart from others is Preston's expertise, passion, and unwavering commitment to helping others improve their communication skills.
Joining the ISA has been one of the best decisions I've ever made. Preston's structured program helped me gain confidence and develop my speaking skills. The interactive sessions allowed me to overcome my anxiety about speaking in unfamiliar situations. I recommend experiencing Preston's program to improve your public speaking abilities.
My name is Milagros Cadillo. I work as a consultant in water and sanitation, as well as a professor in strategy and sustainability at a business school. My experience at ISA has been both practical and highly valuable. As a Spanish speaker, one of the challenges in my English communication has been conveying ideas in a concise and clear manner without losing the strength that my native language naturally provides. The frameworks provided by Preston have been instrumental in helping me structure my ideas more effectively in various situations, avoiding confusion and redundancy. Less is more! Additionally, these frameworks have helped me balance the directness of my message with the necessary warmth--without excess--an ongoing challenge for many women executives. Thank you, Preston. It has been a great experience being part of ISA.
Preston's course was incredibly effective for me - not just because he's so knowledgeable about communication, but because the program felt very personalized. I really appreciated how he took the time to understand each student's individual goals and helped us apply speaking frameworks to our specific use cases. As an international student looking to improve how I express myself in English, this tailored approach helped me make noticeable progress in a surprisingly short time.
Before the ISA, I wasn't able to understand why my points were not coming through in executive leadership meetings. After the ISA, the feedback I had been receiving came full circle in that I could finally understand, through Preston's frameworks, feedback, and coaching, why my points were buried in my thoughts. The ISA is highly recommended and is more directly applicable than a couple of books that I've read about speaking up in business meetings!
Preston has established an Academy that is deeply rooted in community values. With his guidance, I've learned to tackle impromptu speaking with confidence and conviction. He emboldens us every step of the way and equips us with practical frameworks that bring structure and clarity to our communications, without sounding scripted. If you're committed to improving your communication skills and want fast, tangible results, Preston is your guy!
Hi, I'm Taylor. I worked at a Fortune 500 tech company in policy, brand, and marketing. I'm currently on the job hunt. So, I decided to work on my speaking skills to be more competitive in the 2025 job market. Before the ISA, I was overwhelmed and unsure of what I needed to work on. After the ISA, I feel much more prepared to speak and clear on how to be more confident speaking. The ISA is so holistic, simple, and actionable. Preston is a gifted teacher. I recommend him and the ISA to anyone.
Preston -- thank you so much for this program! Hands down the best communication coach! I'm applying the frameworks in real time whenever I am on a teams meetings or giving a presentation. I have been reaping the benefits every single time!
This was a great masterclass. I learned the keys and fundamentals for public speaking. The 80/20 Rule and PREP framework and other strategies are never been taught by anyone and will take your impromptu speaking to the next level.
I sought out Preston specifically because I think he's one of the best communicators I've seen. He rewired the way I think about speaking, and has already made a meaningful impact on improving my communication with audiences of all kinds.
Preston's guidance was instrumental in preparing me for a successful presentation at my job, significantly improving my confidence and communication skills. I've made noticeable advancements in my ability to communicate effectively. I highly recommend Preston to anyone looking to enhance their communication skills. His coaching is a valuable investment in both personal and professional growth.
I enjoyed the various frameworks in ISA. I would tell them to join. It was fun and interactive and we learned a lot and found confidence in each other!
I gained invaluable insights from this course that will significantly impact my professional and personal life. By learning effective communication skills, I'm now empowered to articulate my ideas, showcase my worth, and position myself for future promotions. Preston is an exceptional coach, and I highly recommend this course to anyone seeking to enhance their communication skills and unlock their full potential.
A highly recommended platform that helps alot to improve your speaking and think on how where going to build and construct our story telling on point.
I struggled with speaking confidently and had trouble articulating my ideas before joining The ISA. I followed Preston on Instagram and received an email about this course and thought I should give it a try because I'm struggling to get hired. I feel that with practice I can get better. I think putting it all together and having the Wheel of Fortune game helped bring all the lessons together.
My name is Saoud and I work in Sales. Before I joined ISA, I would struggle with speaking on the spot and my answers would be long winded and had no structure. During the live call with Preston, he put me in a situation and caught my root cause. This was a huge learning for me. You barely find coaches who are able to see the problems right away. Keep up the good work!
The course is great. The frameworks to answer questions is extremely helpful. I now feel more confident in my ability to formulate logical responses.
Before the ISA, I was not confident; will ramble off especially not sure what to say. I chose The ISA because I hope to be a more effective presenter. Now I feel that I have picked up some skills. Like pausing (without using filler words like "so" "because" "and"). And I've deliberately cut down using words like "actually." One of the first lessons on keeping flow was super helpful.
I am a people development consultant. My coaching session with Preston was amazing. I walked away with a critical mindset shift and practical tools i can utilize going forward. I've already begun to use them in my day to day communications.
Before the ISA, I was operating in the dark on how to be an effective speaker, presenter. After ISA, I am improving in my ability to be clear and engaging whenever I am put on the spot. I am focusing on what on Preston Chin's 80/20 rule of impromptu speaking: the 3 core skills: ISA frameworks, simplification (simplifying my messaging) and slowing down.
After I joined the ISA, I began to speak much more confidently and concisely. Thank you so much, Preston, for the great frameworks you've taught me.

Meet Preston, Your Head Instructor:
I never planned to teach impromptu speaking. But it all started in college when I found myself broadcasting Stanford basketball games live on the radio. For four years, I had to keep listeners engaged for 2.5 hours using just my voice – with no script and no second chances.
Those skills changed my career path. I used what I learned to climb from a marketing role to leading business partnerships at the NBA, CBS, and now Lucid Software. Along the way, I built a software company that taught people public speaking skills using AI, taught MBA students leadership communication skills at the MIT Sloan School of Management, and learned from 200 of the best communication coaches in the world.
I've since helped more than 600,000 people improve their communication across social media, which helped me narrow in on where I could be most helpful: teaching professionals how to organize their thoughts and speak clearly when under pressure. Now I've distilled everything I've learned into simple frameworks that have helped hundreds of students land promotions, nail presentations, and speak with confidence in moments that matter.
