Slide 1

“I always found Katy Doan’s professional, well-organized, and exhibiting a strong work ethic. As a Senior Accountant (Fixed Assets), Katy never misses an opportunity to increase her knowledge throughout workshops, seminars, and platform training. I quickly recognized that Katy was a step above most who have been in this position here at the City of Baytown. She was a self-starter who required little supervision. The pride she has in her profession shone through in every work product she completed. She effortlessly completed all tasks and truly made this crucial work look easy. It was this type of performance that gave me the impression that she would move up the ranks within our organization in no time at all. We definitely miss her angel voice as a professional singer.”

Grey Scott, SPHR, SHRM-SCP, Human Resources Manager, City of Baytown-Texas
Slide 2

“As an Accounting Manager, Katy is smart, hardworking, creative and dedicated. She just has 2-day training with a mess of accounting system, but after a month, she made everything professionally in her own way. She did all tasks that are not in her job description. At the first time I saw her, I knew she is the one right away. She cleaned up all accounting software, collection, invoices… and especially helped to do the auditing for the tax filing from previous years and get money back. We love to have her in our team and still keep in touch for every Easter crawfish party & voluntary, charity activities.”

Gretchen McAuliffe, CEO-Co-Founder, Labtopia Inc.-Texas

“As the CEO’s Executive Assistant & Financial Analyst Manager, Katy has consistently performed her duties with competence and often goes extra mile, doing more than expected. She willingly accepts new assignments and whenever she can, ever ready to help others. Cheerfulness, calm and dependable describes best her character. Katy’s stellar academic achievement rubs off in her problem solving and her decision-making skills. Dedicated to the task at hand, she completes them in a timely and conscientious manner. As a strong communicator, when a task requires inputs beyond hers alone, she is able to “rally the troops” to assist. This is probably the best evidence of her leadership skills. She is also a strong table-tennis player, I try so hard to be even with her in some games.”

Danny Hoe Kam Thong, MICPA, MIA, MBA, CEO, Interflour Corporation

“Katy is my close friends in the Catholic choir for more than 7 years. She was phenomenal at everything that she did in choir. She always performed tasks assigned by our Choir Director thoroughly and completely. Not only she finished her tasks with precision, she did them with passion. One such example is when she was assigned to plan activities for a choir camping trip, she planned them in such a way that every member is involved. By the end of the day, everyone had so much fun. But more importantly, everyone felt closer to God and each other. On a personal level, she is super caring and willing to sacrifice what she can to help others. One touching example is when she offered me one of her kidneys when my kidneys failed. I was super happy to know that I have such a good friend like Katy Doan. She is very reliable and always performs her duties with enthusiasm. Best of all, she deeply cares about her work.”

“Katy is a person of impeccable character. Other than professional skills in different areas, Katy has a special touch which is very valuable for a company: “kind and warm-hearted nature”. I remember one instance in a special event that she was invited to sing, she always enthusiastically signs up without the slightest hesitation, eager to help in any way from party organization to cooking food to others. She also organized different charities to collect money for orphan in Vietnam. People with good heart is always making the team stronger no matter of which purposes. By nature, Katy is a perfectionist that impress and bring enthusiast to others. It could be a result of special training school for the Gifted children in Vietnam that she had been educated from. She is a very talented chef, a great singer, a well-performed Master of Ceremonies, a 2020 elected Beauty Queen. Everything she touches, everywhere she goes, I can see happiness, fun and performance.”
