Jennifer Stewart – Los Gatos Christian School

Our Diamond Mind rep was extremely patient and helpful to explain the PCI Compliance issue and what steps I needed to take. Although I haven’t fully completed the process, she has continued to offer herself up for further clarification if necessary. I found her to be personable, kind and very knowledgeable.

Carol Samano – Brooklyn Heights Montessori School

From the beginning, Diamond Mind has impressed me with their efficient and professional manner.

They have continued to provide the best customer service, especially during the setup of our online payment forms. The service is excellent and everyone I have spoken to is professional and extremely knowledgeable. Great service! A very responsive team! Thank you, Diamond Mind!

Susan Weiss – Solomon Schechter Day School

Our school needed to make a big change on our donation page last year. The Diamond Mind rep we worked with was extremely thorough in making sure that our page worked correctly with absolutely no errors. They were quick in their responses and even made suggestions on how to make the form clear and easy to understand. It is always a pleasure working with Diamond Mind.

Debra Hoefs – Cathedral High School

We added a corporate credit card system two years ago and we have had fantastic service from day one. Our representative is always positive, professional and friendly. Return calls are prompt and always with a determination to get our needs met and as quickly as possible. I appreciate everyone that we have worked with from start to finish at Diamond Mind.

Jeanette McCarthy – Episcopal School of Jacksonville

Our Diamond Mind rep has been wonderfully helpful when I desperately needed assistance right away. He was “Johnny on the Spot” and walked me through various screens in order to help me. His patience and thorough knowledge of the Diamond Mind system has been a real relief to me whenever I need help under a departmental deadline. He follows up and makes sure I have what I need. Thank you so much.

Leigh Brown – The Heritage School, Inc.

Diamond Mind has always provided exceptional customer service, but today they raised the bar and went the extra mile.

We are a new customer of Diamond Mind. Our first automatic payment withdrawal is supposed to come out of our bank account while we are out for Christmas break. In order to ease my mind, our representative set up a reminder to check with Comdata to make sure our payment is processed. After checking for us, he will email me if everything goes well, or call me directly on my cell phone in order for us to take care of any issues that may arise. What a relief!

Ari Autor – The Montessori School of Northern VA

I am so grateful for the wonderful customer support Diamond Mind staff provide. They respond promptly on the rare occasion we need assistance.

Mary Ann Brakstad – Francis Parker

Many thanks to Diamond Mind for their ongoing help over that past couple of years. In particular this past week we were asked by one of our departments to set up a new payment process in a relatively short time period with minimal information. Diamond Mind did everything to make it work, even with several stumbling blocks put in our way! My sincere thanks to everyone at Diamond Mind who made this work.

Joanne Demaras – The Benjamin School

We have been completely satisfied with Diamond Mind since we started using them two years ago for our tuition payments. Since then we have added numerous projects (golf tournament, tickets sales, etc.) to streamline the payments that our parents make. It is very easy to setup and use. All of our questions are answered quickly and with immediate results. The software is easy to use and easy to run reports. Everything said, the relationship with Diamond Mind has been a win-win situation

Robert Reiff – United Friends

Diamond Mind has been a great partner for our school. We use their merchant services and have our corporate credit card through their company. Their training, support and customer service is excellent. I highly recommend them to any school in the market for credit card services.

Jean Held – Pace Academy

Pace Academy has received exceptional service from Diamond Mind. The knowledge about the credit card industry that has been available to us from Diamond Mind has been invaluable and has greatly reduced our frustration with setting up credit card payments through Senior Systems software and on our website. In addition, our school has received very good rates for credit card processing fees.

Deborah Danner – Churchill Center

We needed to have credit card processing up and running before a major fund-raising event. Diamond Mind was aware of our deadline and kept us on track to meet our targeted date. They were available to answer any and all questions we had about the process both before the event as well as after. The service she provided was exceptional. We are working with Diamond Mind now regarding online donations and event registration. They have provided samples and suggestions from other schools which have proven helpful. Again, the service they are providing us has been exceptional.

Carlos A. Segura Jr. – Oak Hall School

Diamond Mind has been a integral part in our success to efficiently and effectively accept credit card payments. All the representatives that I worked with made my job easier. Whenever there is a question or issue, they are right there to help. The question or issue is always resolved. I would recommend Diamond Mind’s services to anyone.

Cary Garcia – St. Thomas Episcopal Parish School

The few times we’ve had to call a Diamond Mind, I have truly been impressed with their willingness to help you solve a problem. Even if the problem was not initiated by Diamond Mind. The employees of Diamond Mind go above and beyond what their jobs entail. The representatives KNOW their jobs and this makes things so much easier for the customer. Thanks Diamond Mind for helping our school with all of our credit card processing.

Susan Heglin – Latin School of Chicago

Diamond Mind continuously offer us tremendous customer service support. They always quickly and accurately answer all of our questions and are always happy to go above and beyond typical expectations. Hands down, Diamond Mind is one of the best vendors that I have worked with. I would not hesitate to recommend them to colleagues both in and outside the independent school world.

Liz Carey – Oaks Christian School

Diamond Mind has been a great help to our school in setting-up online credit card payments for our Development department, Booster Club and Campus Store. Diamond Mind also provides credit card processing in conjunction with our online enrollment processor and summer programs software vendor. Our main contact is extremely knowledgeable has been a pleasure to work with!

Timothy Forester – The Hill School

The people from Diamond Mind have always been very helpful. They know the workings of the credit card markets well and have maintained great patience when dealing with our questions. The pricing has been very competitive, the services offered have been terrific. Could not ask for more. Now whenever our school is looking into new online solutions the first thing I do is contact Diamond Mind to obtain their perspective, and recommendations.

Paul Mayhew – River Oaks Baptist School

Diamond Mind has become a valued partner with our school offering a full range of cost effective solutions to meet our needs. From purchasing cards to merchant processing, Diamond Mind has helped us to streamline functions in the Business Office, Development Office, and campus wide.

Kelli Stueve – The Pegasus School

Making a change in our online tuition payments was not a decision that we took lightly. Would parents have difficulty with the change? Would the transition be seamless? Would the new payment gateway integrate easily with our website? Parents are excited by how simple it is to enter their child and payment information. Diamond Mind asked the right questions, provided hands on assistance, created demo sites for our review, and made the entire process seamless.

Julie Vecchitto – Hotchkiss

We were introduced to Diamond Mind a number of years ago by our web company. Since that introduction, we have expanded the number of services we offer online from an online giving form to event registrations, school stores, and most recently, Diamond Mind’s tuition portal. They are always available for consultation, training, and questions, and help us integrate our online payments with our website. Their training sessions with our users have been very helpful I would definitely recommend Diamond Mind.

Tim Mulvenon – Head-Royce School

We have only been with Diamond Mind for a couple of months, moving not only our merchant services but also our corporate credit card business to them. In addition, we are setting up the only payment services for tuition and fees through O-Matic. The transition has been seemless, the setup fees reasonable, and the service level fantastic. Diamond Mind really understands independent schools, something that the majority of merchant and corporate credit providers do not. I couldn’t be happier with our transition.

Amy Kenney – First Presbyterian Day

We have been working on setting up online giving on our website. We were set up with another merchant previously and the situation was a nightmare. Whipple Hill referred me to Diamond Mind and you guys have been a lifesaver! I am the webmaster for our school and have limited knowledge in anything about banking, billing, and credit card processing and you have done an amazing job of simplifying everything for me. Always quick to respond and help in any way. Thanks for everything! I’m so glad to say we have been able to connect with Diamond Mind and get it working in a very efficient manner. I couldn’t be more pleased.

Bob Cohn – Marin Country Day

Years ago, Diamond Mind reduced the school’s credit card fees and have maintained the same low pricing ever since. In addition, when I have any questions regarding credit card processing administration, costs, website changes, etc. I call Diamond Mind first. It’s always a pleasure doing business with Diamond Mind.

Ivette Lancaster – Isidore Newman School

We have been a Diamond Mind client for several years. As we look for different ways to provide service to our community, Diamond Mind has always been helpful. We are not in the same place we were when our relationship started, and Diamond Mind has been able to support us in our growth and endeavors.

Breanne Warkenton – Sage Hill School

I couldn’t be more thrilled with the customer service that we’ve received from Diamond Mind! Any time I have a question about cards or the website, Diamond Mind is always extremely helpful, approachable and friendly! They never seem to be put out by my frequent calls and emails trying to understand the system. This is the first time I’ve really sought out the opportunity to give a testimonial about service that I’ve received, but I felt compelled to because I have been so pleased. You have a great team of people working for you!

Lara Roth-Biester – Riverdale Country School

The staff at Diamond Mind is professional, smart, speedy, friendly, and always obligingly no-nonsense. They treat substantial and minor requests with equal care, and just get it done. Couldn’t ask for better.

Chuck Gott – Village Christian School

We have been happy with the services of Diamond Mind for our online credit card payments. We have a variety of options for paying by credit card and they work well. Whenever we need assistance in setting up new forms or changing credit card options, we receive prompt accurate attention. Occasionally we have had to make last minute requests and Diamond Mind has come through for us every time.

Judy Kennedy – St. John’s Episcopal School

With my first phone call to the company looking for advice on products and whether Diamond Mind could fulfill our needs – I was so impressed with the team! When it came to tech support I knew we did the right thing signing up with Diamond Mind. Patience, courteous, knowledgeable and always willing to go the extra step.

Connie McGee – Battle Ground Academy

Making the switch to Diamond Mind for our credit card processing has been probably the most seamless transition I have ever experienced. This is due in large part to the excellent customer service we receive. Our contact is extremely knowledgeable about Diamond Mind products and how they can benefit our school. I never hesitate to call with a question and she is always eager to help. Reporting and reconciliation are simple and easy, which was a major issue with our last processor. We are going live with the Tuition Portal in a few weeks and are excited about the new options it will give our parents for paying tuition.

Minda Turner – Providence Day School, Inc.

Partnering with Diamond Mind in providing the merchant services and corporate credit card for our school has been great! Retrieving reports from the payment gateway is easily accessible which helped in costing the fees charged on the credit cards and identifying the revenues generated from individual programs. The corporate credit card has helped in the payable cycle and cut costs in generating payable checks. The staff are very helpful in setting and implementing the services they provided. All in all, it is a great investment to partner with Diamond Mind, I would highly recommend this company to anyone!

Matthew Vaughan – Union Theological Seminary in the City of New York

Our organization reached out to the team at Diamond Mind during a summer of intense transitions for us; their thoughtful work helped lighten the load. At every step of our interactions with them (from phone conferences to emailing) they were responsive and helpful. Both reps that got us set up were courteous and customized a solution that was right for us. We are very happy with the service we have received. Thanks!

Robbie Brenner – Lawrence Woodmere Academy

We have found Diamond Mind to offer excellent credit card processing rates as well as great service from donation page design to credit card swiper orders and technology.
