" As someone who typically prefers to solve everything by herself, I was hesitant to try coaching initially. I am so glad that Tee changed my mind; working with him has transformed not only my working habits, but shifted my relationship to productivity itself. He is extraordinarily insightful and easy to talk to, and I highly recommend him to anyone who is struggling with their work and motivation. "

" I strongly believe that Tee's style of coaching is valuable across disciplines.
My time working with Tee was valuable in such unexpected ways. Having known him in a professional, but not in a coaching context, I expected a different experience. Ultimately, the conversations... helped me crystalize some of the noise in my own head about the direction I want the next phase of my career to take....The guidance and feedback that Tee shared helped me uncover some things I already knew about how to best structure my work and personal lives to create the circumstances that allow me to do that work in a way that works for me."

" Working with Tee has been hugely helpful in challenging and changing thought patterns that were holding me back from operating at my highest level. Tee is excellent at quickly getting to the root of a problem, and offering models, perspectives and tools to help resolve them - all within one session. I've been impressed by the range of topics he's able to provide acute insights on. He is also a great communicator and fun to work with! I highly recommend trying out coaching with Tee."

" The reason I keep going back to sessions with Tee is that he consistently highlights false dichotomies and unnecessary constraints that I put on my thinking, and that limit my options.
This does not always lead to amazing changes, but it is a key element of positive change that Tee can provide reliably."

" Tee is the smartest coach I’ve ever worked with. With just one coaching session I solved the problem I had for the first 2 years of running my business, namely alternating between working myself to death/burning out/boring out/getting back to overwork.
I like to think of Tee as a brain engineer that will help you solve the bugs in your thinking/mindset, and also give you tools that you can use yourself on a daily basis to improve your thinking and your life.
I recommend Tee to any person who wants to radically improve his/her life though better introspection and thinking. "

" Through his careful listening, lines of questioning, and thoughtful examples drawn from his experience, I've developed more clarity about what I want in life. He's teased out the blockers that prevent me from getting stuff done, such as lingering narratives and fears, and identified models I can mold to unblock myself in other situations. If you're a motivated and self-aware person that is seeking more clarity (even if you're early on in your career), self-improvement, and want to face reality with a coach who'll tell you like it is, then I highly recommend Tee."

" Working with Tee has been helpful and impactful for me, even more than I had expected. I've thought of myself as someone who takes a critical eye to my own assumptions, yet Tee quickly identifies narratives I've still been unknowingly working under (particularly about my own interests, interactions with others, perceived abilities, etc.).
It's remarkable the extent to which just recognizing a narrative's existence opens up a wider array of options; while working with Tee I've ended up changing my behavior in a number of concrete ways to great effect because of this. I suspect many people would benefit from this kind of insight in coaching--even, and perhaps especially, people who consider themselves decisive as leaders. "

" Tee is quite the coach to have in your corner. Rather than coming in with preconceived notions about what's right or wrong to do in business (which many folks do), Tee's unique approach helps deconstruct your own thoughts and weed out your own cognitive dissonance. He helps you realize the answers to your own problems in a way that creates internal consistency and alignment. Not to say that "business-wise" mentors can't play a good role. But, I believe what Tee brings is something unique that CEOs need to operate at the highest levels."

" I am really benefitting from Tee's coaching. Tee is an attentive and perceptive listener, and has a range of insights, tools and further reading that he can deploy to help you think differently about a specific challenge you're facing. It's early days, but it's already had a noticeable impact on how I think about my day-to-day role as a leader of a non-profit. I highly recommend Tee as a coach. "

" Tee has given me the tools to channel the immense pressure and stress from running a startup into a work environment that is not only sustainable, but one that I am excited to experience daily. Tee’s approach is wholistic and has allowed me to completely reframe how I value my time and the emotional labor of being a leader. I cannot recommend Tee enough for anyone who is trying to “unstick” themselves while continuing the work they love. "

" As a coach and manager myself, I went to Tee to learn from and be humbled by the Coach of Coaches. I didn't need more than that to be content with the coaching I'd receive from Tee - but we've gone so much further beyond. Tee has patiently and gently reshaped my relationship with my work, with myself, even through one of the busiest, most stressful, and most reactive periods of my career. Looking back at it all I'm honestly baffled at how he does it "

" Tee’s a cross between a psychologist, a philosopher, an epistemologist and a friend and, in my search for someone that could help me understand myself and the world, after several psychologists and coaches, Tee shines bright.
I honestly don’t know what to prioritize. Everything me and Tee talked about is so important...Tee is a catalyst for error-correcting your self-knowledge and in the process you’ll figure out which beliefs are true, which ones are holding you back, which ones are relevant and which ones, even if true, don’t matter all that much.
...now I enjoy a very deeply meaningful set of friends with which I go out every weekend and my romantic relationships...have dramatically improved...
Tee [also] helped me to understand how to think about my professional path and create a fully integrated plan.

" I think it's not an exaggeration to say Tee is the best coach/debugger I've had. Highly recommended!
Tee is attentive, perceptive and wicked smart. He's also deeply kind, and his nonjudgemental approach gives coaching sessions a feeling of open space to really go into what matters to you. From only one or two sessions, I got concrete benefits that I still use regularly almost a year later.
Specifically, Tee changed the way I think about personal problem-solving: I used to ruminate and get stuck looping between two contradictory thoughts/feelings, and because Tee showed me a way to navigate them...I now find it very easy to make progress and un-stick myself.

"As CEO of a new organization, I have found Tee's coaching very valuable for navigating thorny issues that arise and finding my leadership style. He is skilled at moving our sessions forward while still letting me guide the direction.

His coaching has equipped me with new tools and perspectives as an individual and a leader. I'm grateful for the progress we've made together."

" Tee Barnett Coaching has been really helpful for me across a range of areas, from the practical to the theoretical. We've explored areas from the meaning of intelligence, to the role of a CEO, to building operational systems, to impostor syndrome. I leave each session with a whole lot of new insights, and an option to innovate and improve in my professional life. Tee creates an environment that is approachable, curious, and completely non-judgmental, and balances the roles of supporting, suggesting, and listening exceptionally well. "

" Tee is a kind and thoughtful coach. He was careful in asking questions that would help both of us to understand how I perceive situations and how misperceptions are limiting my ability to do good work and have meaningful relationships. He was generous enough to go into some difficult issues and did so with care and compassion. The coaching has helped me to identify mental and behavioural patterns that are holding me back, and provided me with some strategies to correct these."

" My sessions with Tee have helped me to unpack professional and personal blocks that felt too difficult to sift through on my own. Tee asks thoughtful and clear questions that help me sort through facts and stories and get to the core of what I really want. Together, we have been able to develop language and framing that helps me to gain a deeper understanding of my emotional and rational reactions, and then develop personalised strategies to enhance my performance in the future.
I can feel myself gaining confidence and resilience in handling potential set-backs, learning more about myself and improving my ability to communicate my needs with others."

" Working with Tee has been an extremely valuable and insightful experience. He has asked questions I would not have considered on my own - which has helped me probe deeper into my mind, uncovering beliefs I would have not otherwise been aware of, and processing through them. Tee has offered practical systems and solutions, such as root-cause analysis and meta-thinking to assist me in solving problems.
Tee is very personable, with a knack for organically nudging conversation in the right directions. He has a unique ability to navigate thought-spaces to obtain precise insights - using them to formulate actionable solutions."

" Working with Tee has been very beneficial for several reasons. First, it allowed me to refocus my attention on high-level issues/considerations, which is helpful when developing a team strategy and goals.
Second, I learned some new transferrable skills (e.g., how to think more strategically, how to provide better arguments to support my ideas and/or convenience others about my approach to a problem/situation etc.).
Last but not least, exchanging ideas with Tee and hearing his perspective on different topics contributed to the generation of new, tangible ideas that I am hoping to utilize at my work.
In summary, working with Tee allowed me to gain a better and more holistic understanding of my strengths and limitations, which I believe will allow me to have a higher impact in my current role. Many thanks for the pieces of advice and sharing your thoughts with me!

" Tee is one of the most emotionally wise people I've ever met. Just being around him makes you feel more calm and confident.
He has a way of cutting to the heart of an issue in a compassionate and empowering way.
He makes you want to be more productive while also feeling happy with how you are in the moment and not having to always be self-improving or doing better. He gives you this feeling of being enough and that things are OK.
He does an amazing job of skillfully using a wide array of psychological techniques without you even noticing them. And then he does the best part for an EA - he explains what he was doing so you can understand it - and yourself - better.
Tee is a fantastic coach. I highly recommend him if you want to be happier and more productive."
