I am incredibly pleased with the service I have received from Hayden and her team at HBH. I'm working with an Executive Assistant. Their support each week has been dependable, and extremely helpful. I spent a great amount of time researching the best fit for my assistant/support needs, and I'm grateful for choosing Handled. By Hayden!
With the support of Hayden and her team, I am now able to focus more on my clients; I am feeling less anxious, and I am earning more. So it is with great enthusiasm that I recommend her services to other executives and entrepreneurs!
A consummate professional, Hayden is reliable, collaborative, and quickly adapts to new projects. Her skills and competency are broad.. She and her team have been especially helpful in supporting our annual conference. Responsive, thoughtful, and kind -- she's also a true pleasure to work with! I highly recommend Hayden; she would be an amazing asset to any organization.
As a local medical practitioner and business owner, I was worn very thin when I met Hayden through a local networking group. I felt like Hayden truly saw me; she has a unique "get it" quality. I quickly connected with Hayden's genuine and nurturing, yet pragmatic and effective approach. She provided my business with a full consulting overview, recruited for and placed our new practice manager, and I am now working with the HBH & Co. team on long-term development strategy and support. Working with HBH lifted such a weight off my shoulders, enabling me to bring balance back into my business and my life again. I am no longer buried in the day to day of my business, I can now grow and succeed more sustainably, and I couldn't be happier to have such a trusted and uniquely experienced team supporting me along the way.
Together, we help you step into your role as the Empowered leader of your business, to achieve greater success, balance, and joy.
