This is a competent and reliable business. Nikhil is a proactive problem solver and helped us maneuver through long-distance notary services with our wheelchair-bound sister several times. He quickly grasps the problem, suggests ways to accomplish what is needed at reasonable prices. An outstanding professional.

The best customer service I’ve ever seen!High efficiency and quality in all the services offered!!Thank you Nikhil

Fantastic experience; friendly, fast and efficient. Thank you!

I have been going here over the past year or so and have always been very impressed with the services and products received. From shipping to mailing to printing and notary, this is the place I prefer to go. Nikhil the owner is kind, helpful, and goes above and beyond to assure your needs are met. He went well over above and beyond helping me with shipping and other needs for a move. I couldnt recommend this store any higher - reliable, honest, friendly, and great quality. I will miss having this as my go-to local neighborhood shop!

I found the business via reviews as I was looking for a local mailbox. The reviews were great and I can understand why. The mailbox rates are very reasonable compared to other shops. Shipping services are reasonable too. If you have any shipping questions - youll get an honest response. The owner and workers are dedicated and you wont go wrong supporting a local business. Give them a try and see for yourself!

Nakhil, the owner of Cornerstone Copy in Walnut Creek, runs an excellent business, and I have grown to rely exclusively on him for all my copy, printing, and mailing needs. I dont go anywhere else, because I know Nakhil knows me best and will give me the best service. He is super- patient, listens carefully, and can multi-task under pressure! He knows most of my mailing addresses in his computer by heart, and he makes sure that every detail is covered. I have never had a glitch with anything I have sent through him. I feel that he really looks out for my needs, and puts me first as the customer. He is also a notary, which is very helpful, since I have needed that many times since my Dad died. I always feel that I am the only one that is important when I am in Nakils store. He devotes his entire attention to the client at hand, and performs his work with a smile and good cheer. I wouldnt go to anyone else! And there is always parking too! ...And doughnuts next door! Thanks Nakhil!

Excellent service! Thanks, Nikhil!

Fantastic local shop for everything mail. Been coming here eight years but with the new owner Nikhil its the best its ever been. Great pricing and service with everything you could possibly need. Beats the lines and incompetence at the new merged Fed Ex or slow as molasses post office and right in the middle of Walnut Creek.

I found this business today and stopped by to get some business cards created. The service and quality was A+. They were friendly, very quick, and all at a great price. Ill surely be back.

What a great place! Came in last week to talk to the new owner about my mailbox, and placing a vacation hold on my mail/packages. Super helpful, and friendly. Highly recommend this place!!

Convenient, welcoming, knowledgeable and always ready to help. That must be the motto at Cornerstone Copy & Mail because they deliver in all those areas. Nikhil, the owner will always make sure you are well taken care of! 5 + stars for sure.

Great neighborhood store! They ensure that all my print orders are done correctly and on budget (they even let me know about helpful tweaks and adjustments to reduce the cost).

Rip off!! They charge almost double to ship packages! You are better off going to the post office.They also do not post their rates, which is concerning.

This location is convenient for me and I can avoid having to go the Post Office and waiting in long lines. I have used this store for certified mail, notary services, purchasing envelopes, lamination of cards, etc. The staff is really great and the service is excellent!

Cornerstone is my go-to place for printing, copying and shipping. Reasonable prices, excellent service, and free parking.

Nikhil is great to ship with and does a great job packing items for me

What an awesome neighborhood place!!

Fast friendly service. I will come back here again!!!

Friendly service

Awesome service!!!!!
