Owner of Berkshire Hathway

Today I ordered 500 4X6 Holiday Cards. They had incredible customer service. They helped me make adjustments to my format and made suggestions to improve the look of my holiday card. The cards have not came in yet, but thought I’d review their customer service before I forgot. I’ll try and update you all on the quality of their work. I’ll warn you ahead of time that I might forget to update you if the cards are good. Cards were terrific quality! Ran into this review today, had to update it.

Owner of Fashion Denver

I’ve been working with GtG Custom Print for about a year and I have to say, they have REMARKABLE customer service and SUPERB quality. I used to do business out of state for affordable printing but now I’ve found my go-to, in the city, support local, favorite print shop ever! I’ve had banners printed, flyers printed, and even t-shirts made and I know that I can always count on them! Support Local!!

Owner of Leap Dance Studio

We’ve had flyers, posters, and shirts printed here. Everything turned out great. They are fast, friendly, and produce quality work with reasonable prices.


This has to be the BEST place for promotional materials! Hue was fantastic and the creativity is superb! Thank you! I will always refer businesses/ organizations to you!


We have been producing Movie In the Park events in Denver for a few years, and have used many print shops for our flyers, but we only use GTG now. They produce the best quality prints on much better paper than we have ever received, and for full-color handbills, high-quality details are important. The owner is also incredibly friendly, responsive, and a supporter of the community. I highly recommend them.

Owner/ Lead Singer of Jerry & Joy Music Band

Seriously, GTG cannot be beat. We have ordered merchandise from them for years and the prices stay low and the work only exceeds expectation. The staff is knowledgeable and friendly and makes every accommodation for us. Thank you Hieu and crew! We are always happy with your products.

Owner of Bounce with Tigra

I found GTG custom print on FB, GTG custom print is one of the best company in Denver, Colorado. Super fast service, reasonable price, friendly customer service. For three weeks they did all my marketing packet … T-shirts, car magnets, flag, stickers, Car Wrap and much more.

Owner of Sasha

I’ve worked with Hieu and GTG for the last two years and I absolutely LOVE this company. I organize annual conferences for 250 high schoolers. Hieu made the whole process of designing, ordering, and picking up t-shirts for the events a total breeze. The garments were sweatshop-free, affordable, and looked fantastic!! There was also a super fast turn around time, even with the large quantities. HIGHLY RECOMMEND!!

Owner of Asian Avenue Magazine

I have worked with GtG Custom Print several times! And each order has turned out wonderfully! They are great to work with – fantastic customer service and speed! My t-shirts have turned out really nicely and I would not recommend anywhere else. They are a great printing company, located off Federal Blvd and Exposition!

Owner of Christina Pham

I’ve been going to this business for t-shirt printing for years now. The staff are friendly, accommodating and overall great to work with. The quality of work can’t be beat; especially for the price. Orders are always done fast and my expectations are always met and exceeded. Hieu and his staff are definitely the people I think of first when I need any printing services done.

Owner of Top Ten Nails & Spa

I have been using GTG Custom Print for years now. The owner is awesome to work with and has done an excellent job with all the shirts he has printed. There has never been a mistake with the printing and the shirts come out looking great every time! Not only is the quality of printing flawless, but the shirts were ready on time. I wouldn’t go anywhere else in the Denver metro area to get my printing done.

Owner of Snowlab Restaurant

I’ve been getting my shirts printed here for years. Not only shirts but business cards, banners, stickers, embroidery, etc. were all done exceptionally. Their prices are lower than most (trust me, I’ve checked) and their staff are very friendly. I highly recommend this business.


My organization has been using GTG for all our printing needs for the past year (small format, large format, and t-shirts). Everything we’ve gotten from them has been of incredibly good quality, and their service is always timely.
As a side note, Hieu, the owner is the best kind of person to work with. He has, on numerous occasions, recommended us the more cost-effective option rather than having us overpay for something we don’t need.
Definitely a good place go for printing and design.

Owner of Pho 9

This company has great service. They are very fast and professional. Even with amazing business professionalism, GTG custom print contains the most amazing people. They not only provide the best customer service, but individually talented and skilled in their own ways. Together, I have to say hands down and amazing company.

Owner of KG Clean

I have been working several versions of a company brochure, GtG helped make the ordering process simple and easy. Not only are they a Colorado born small business, but their prices are competitive enough to justify using small a business rather than a large bulk order site.
Keep up the good work GtG staff! I look forward to having my print needs handled by such professionals.

Owner of Elevate Denver

Our church and organization use GTG for all our printing needs! Even with short notice, GTG always comes through for us! They have wonderful customer service, excellent quality and great prices! I definitely recommend using them for all your business needs!

Owner of Agape

Hieu is a great person to work with!  He’s very friendly and knowledgeable about the shirt business.  He makes sure that I have the highest quality shirts at a reasonable price.  His customer service is outstanding, and he even went out of his way to pick up my order from production because I needed it quickly!  His commitment to serve his customers is unremarkable and what makes him and his company unique.  I highly recommend ordering shirts through him because you won’t be disappointed!
