We'd like to personally invite you to explore what makes our practice unique and special.

About us.

It started as a friendship in dental school that transformed into a business 9 years later. A group of dentists coming together to provide a well-rounded practice aiming to help its local community.

What sets uspart at Dentist Tree of Fairfield is that we are a husband-and-wife team with more than 20 years of dental expertise.

Meet the Doctors

Dr. Katy Poramapornpilas

As a Houston native, Dr. Katy Poramapornpilas always dreamed of opening a private dental practice in her hometown. She’s excited to finally make her dentistry dream a reality with Dentist Tree of Fairfield. She graduated from the University of Texas at Austin with a Bachelor of Science in Nutrition and later attended the University of Texas Dental Branch at Houston, where she received her Doctor of Dental Surgery degree.

Dr. Katy has since practiced at several offices in her home community, and she loves helping her fellow neighbors smile bright and happy here in her own practice. Dr. Katy doesn’t just want to provide patients with exceptional dental care—though she does that too by staying updated on the latest developments in the dental field. She also makes dental visits stress-free and fun! With her friendly, compassionate personality and fun signature tooth earrings, she has a talent for making patients smile in the dental chair. And as a parent herself, she’s a great hand at caring for younger patients. No matter your age or your smile’s needs, you can stay content and confident knowing that your smile is always in the right, expert hands.

Out of the office, Dr. Katy loves and cherishes her time with her husband (who you may recognize) and children. Her outgoing and adventurous personality means that she will try almost anything at least once. Just look at her music taste, which is an eclectic blend of hip hop, country, alternative, oldies, and more! Dr. Katy also enjoys traveling, exploring various foodie options, and spending time outdoors. Like her husband, she is a huge sports fan and loves rooting for the Texas Longhorns and all Houston sports. However, she’s no stranger to trying her hand at them too, playing volleyball, basketball, tennis, and (attempting to) golf in the warm months and snowboarding in the winter.

Meet the Doctors

Dr. Hieu Nguyen

Dr. Hieu Nguyen is a proud Houston native who loves helping his patients here in Cypress. He graduated from the University of Texas at Austin and received his Doctor of Dental Surgery degree from University of Texas Health Science Center at San Antonio. With the burgeoning development of the city and all of his family residing in Houston, he felt it was only natural to return home and give back to his hometown community. To Dr. Hieu Nguyen, dentistry is not just drilling and filling, but the perfect blend of art and science.

Although he loves many facets of dentistry, Dr. Nguyen most enjoys getting to know his patients. To him, the heart of patient care is taking a personalized approach because each patient and their smile is special. Whether a patient’s concern is cosmetic, restorative, or a dental emergency, Dr. Nguyen creates a genuine connection with his patients and provides them with the excellent, individualized care they need. Dr. Nguyen also attends seminars annually to learn about the latest technologies, procedures, and materials in the evolving dentistry field. This helps him provide comprehensive care for patients of all ages with an ease borne of hard-earned experience.

Dr. Nguyen is a family man who loves spending time with his wife (who you may recognize) and two children. He couldn’t be happier than when they’re all together, whether that means watching movies together or spending time outdoors playing sports. Like his wife, he is a big sports fan, and his love for his hometown means that he’s always rooting for the Houston teams. Luckily, this is something that they both enjoy doing together. Dr. Nguyen also loves to cook, and he makes a habit of meeting his family’s adventurous and high foodie standards.

Our patients say.

“I wish I could give them 10 stars! This was my first time here and they were so incredibly friendly. The office is very clean and modern. I loved Dr. Katy! She is so sweet, patient, and understanding. I was a little nervous since I’m getting my wisdom teeth out, but after meeting with Dr. Katy and her staff, I’m feeling a lot more comfortable about the whole process. Awesome dentist all around!!”

Gina B.

“Our whole family sees Dr. Katy and Dr. Nguyen and we have nothing but compliments for this office. They are experts in their profession and actually care for their patients. I've gotten some complex work done here plus the basic exams and cleanings and it's always been a good experience.”

Marcus J.

“I was going to a local dentist here for years and became very unhappy because I felt like they were looking for ways to jack up the prices.”

Vanessa P.

“I came in for a cleaning & the hygienist did a great job. The first time I ever felt that my teeth were clean after a cleaning. The hygienist even took the time to floss between my wire retainer. Everyone was very professional & engaging. I highly recommend.”

Sane R.

“The staff are very accommodating. The place has a calm and hygienic ambiance. Victoria and Dr. Mieu really did a good job in explaining and doing the procedures. The best dental clinic so far I’ve ever been too.”

Keith A.

“Great experience at Dentist Tree. The staff are all very friendly. They do a great job of explaining any issues and treatment options. The office is modern, comfortable and clean. The TV’s overhead with Netflix are a great distraction while they are working.”
