About Us

Tina Hallis headshot
Positivity Expert, Tina Hallis, Ph.D.

Do you wish your people spent less time feeling overwhelmed and more time at their best? Are they struggling with change? How about communicating and connecting more effectively with customers and each other?

Tina Hallis, Ph.D. is a professional speaker & trainer who works with organizations to improve morale, teamwork, and ultimately productivity by teaching their people how to shift the way they think about their jobs, colleagues, and customers. The result is more resilience, less stress, improved relationships at work and at home, and increased POSITIVE performance.

Tina is certified in Positive Psychology through the WholeBeing Institute, an Authorized Partner for Everything DiSC®, and a Professional Member of the National Speakers Association. She worked for 20+ years in Biotechnology at small start-up companies and large corporations before discovering a new science called Positive Psychology that focuses on how we can all live our best, most meaningful lives. She knew she needed to share this life-changing information, so she decided to create her own company dedicated to helping people and organizations find their “Positive Edge.” She now focuses on helping people break out of their negative thinking so they can be more positive at work, at home, and with each other. This not only makes work more enjoyable but also makes organizations more successful.

Tina has had the opportunity to share this information with thousands of people from a variety of industries including government agencies, academic institutions, medical institutions, financial institutions, biotech companies, manufacturing companies, sales teams, nonprofits, associations, and more.

Testimonials For The Positive Edge

  • Thank you for your time, facilitation and expertise at our retreat last Friday. We have received such positive feedback and have already noticed a difference in implementing our newfound knowledge with having a better understanding of one another.

    Tina Whitehorse Executive Assistant at UW Health
  • The time you spent with us presenting the DiSC workshop was great. Our team really enjoyed better understanding our own and others’ personalities and work styles. Little pieces like how to work best with each other and what style we are have come up in conversation on numerous occasions since. I really believe it brought us a lot closer.

    Laura Portz Innovation Consultant, Innovation Team at American Family Insurance
  • Our sales team overwhelmingly chose Tina’s presentation on DiSC personalities as a highlight of the 2-day event. Tina was professional and skilled at engaging the audience, and got our often reluctant group moving. I was particularly impressed at how well she was able to adapt her presentation to fit our company culture and professional field.

  • Building Positive Connections (Understanding and appreciation our differences)

    We don’t observe the world, we interpret it based on our own personal perspectives. Because we all have different life experiences and different personalities that shape our perspectives, this can make our interactions challenging. What’s more, our brains trigger a “threat” alert when we meet someone with different preferences than us. Understanding and reminding ourselves that these differences are not bad, but interesting, improves our ability to connect, collaborate, and communicate with the people around us. This interactive program uses Everything DiSC® Workplace assessments to help people understand their own personal perspective and how to identify and adapt to those of others.

  • Solving the Mystery of Customer Quirks (Strategies for Building Better Customer Relationships)

    Customers buy from people they trust. That’s why building strong relationships with customers is key for successful Sales and Customer Service. Yet every customer is different and some can be more challenging than others! This engaging program is all about how to overcome these differences so we can relate to these people and connect at a deeper level by learning how our brains work in social situations and understanding personality and buying styles based on Everything DiSC® Sales assessments.

  • Finding Sanity in Ambiguity and Uncertainty (Building resilience in times of transition)

    It’s natural to worry about how upcoming changes in our organization will affect our work and lives. In fact, we’re wired to anticipate the worst possible outcome. Although this is an important part of our survival instinct, there are things we can do to shift our thinking and stay more positive. Instead of feeling anxious and stressed, we can get better at focusing on the opportunities that the change may bring. The result is a more enjoyable work experience, a smoother transition, and higher productivity.

  • Winning the Mind Game of Sales (Using Science to Minimize Stress and Maximize Results)

    We often hear that succeeding in sales is a numbers game, yet anyone in sales knows, it’s also a mind game. To provide the best customer experience, sales professionals need to bring a positive and optimistic attitude to their work everyday. In fact, studies show that positivity and optimism drive sales results. Yet constant rejection and challenging customers can drain their energy and motivation. The great news is that increasing our optimism is something that can be learned. That’s where this program’s simple but powerful, science-based strategies to build optimism and resilience can make all the difference.
