What They Say

Featured on

Tina is the consummate HR professional - she excels in all the things HR should - people, processes, organizations - but importantly, she also excels in learning about the business.

Tina takes the time to understand not just what business leaders say their priorities are, but also to learn how the business actually runs, why it is organized the way it is and who are the key stakeholders to influence so she can better translate priorities into action.

Tina also sees the big picture on employee health and well-being and how to transform culture from middling to high performance.

I highly recommend Tina to any organization who values its employees and wants to improve the most important asset they have - people.

Senior Energy Executive

FOrmer-CEO Avangrid Networks

Tina is a great person to work with and an effective HR partner. While supporting my organization, she was able to understand the critical business needs, strategize on critical plans to address them and implement. She and her team were never afraid of taking a “hands-on” approach whenever needed, which was truly critical in getting things done. Tina never shied away from communicating with leaders, regardless of the topic being an easy or difficult one. I really enjoyed working with Tina and having her as the HR partner supporting my organization.

SVP Operations Avangrid Networks

I found Tina's insight and thoughtful approach to be very valuable in working with my direct reports and the organization. Tina helped us drive execution in the Company that had significant impact on people, processes, and systems, resulting in annual synergies of over $15m. She became a trusted confidant of the team.

Mark Conte
Chief Accounting Officer

Smart. Honest. High integrity. Solutions-oriented. Many of these buzz words are thrown out there when people look to describe themselves as they market their skills for opportunities. Tina does not have to do that, because she has connected with tons of people who gladly will do that on her behalf.

Tina is a driven professional who takes her work seriously, and is never encumbered by job titles. She is truly one of those individuals whose character shapes the position; not the other way around. She is collaborative, but about the outcomes. She is flexible, but focused. She is loyal. In essence...she gets things done!

I am proud to have worked with her, and admire the way she conducts her business. She is a treasure and a leader for any organization.

Galina Grigorova

Director Agile Enablement, Corporate PMO, Point 32 Health

Tina would be an asset to any small business looking for guidance, consultation, and hands-on support with any HR-related need. She is smart, direct, tactical, empathetic, and has integrity. When she began consulting, she helped me navigate a difficult personnel situation, and she created our employee handbook. I could not be more grateful or happier with the outcome. I cannot recommend her strongly enough.
