Written Testimonials

All the programs that I completed are very informative. I am not sure if I can pick a favourite because they are all equally good. My customer service skills are enhanced and improved since commencing your programs. The information I learned is always at the forefront when interacting with my colleagues and clients. One phrase that really stuck with me is, always surprise your customer. This, in my opinion, forms the basis for excellent customer service.

SQI with its programs for managers and employees provides comprehensive knowledge which I missed getting a professional economical education as well as professional training’s. Every organization who serve customers have to learn how to do it proper otherwise they just loose customers meaning their money.

No one in the entire world will give you as much as SQI does.

Banco Promerica (of Grupo
Promerica) is a regional commercial bank throughout Central America, Panama, Ecuador, Florida, USA, Cayman Islands and the Dominican Republic. We have over 950 branches and  over fifteen thousand employees whom are trained regularly with the one single focus: Empower the staff and provide our customers with exceptional service.

There is no secret to our outstanding success. Well, at least not for us there isn´t but the competition thinks we´ve got one. For us the customer is first…period. That´s the secret! Well, that´s one of them. Creating a culture around that premise has been our relentless effort for decades. We continue to improve the customer service by constantly training and developing our staff. 

Our other secret has been finding John Tschohl, President, CEO and founder of The Service Quality Institute and utilizing all of their wonderful and creative, customer service training programs. Add to that, the personal coaching John has provided to us over the years. Through his guidance, we broke the mold to the traditional and standard Monday through Friday banking. We designed innovative programs throughout our branch system such as opening for business, every day, at 8:00 a.m. and staying open until 7:00 p.m. daily, and until 9:00 p.m. in
strategic locations.

Our most current innovation, and keeping us ahead of the competition, is a service guarantee of a maximum 20 minute waiting time to be served at the teller line. Proudly, last year we achieved  99% of that goal.

We appreciate the relationship with John and SQI and are very thankful for their guidance, coaching and outstanding training programs for the past 20 years.

Good day, good sales and service. We´ll meet you at the top!!!

Margarita Valle, Customer Service Manager, Interairports, S.A. Honduras

“Grupo Terra won the concession to manage Honduran airports in 2005, it wasn’t until 2013 that the company decides to create a customer service department. In 2016, after years of planning and pitching ideas plus the Groups growth plans we developed the service culture plan for the Group.

Grupo Terra vision shifted towards service, in 2013 the hired me to develop the Customer Service department, immediately I reached out to Service Quality Institute to help me create the foundation of our service program and define the basis of our culture.

My approach to cultural evolution was designed with one aim in mind – to help our organization become the best service provider in Central America. We spend significant time with the key people in our organization to understand the current culture, define aspirations, and set a winning path. Our path before SQI, was as many companies operate today, customer service was present but not a priority. After the SQI we shifted our mentality, plans, and focused on customer needs.In 2019 we won two international awards for customer service. Everything we have accomplished has been thanks to programs like Service Quality Institute and an amazing team that work non-stop to make every passenger journey, pleasantly”.


Dear, John, we really enjoyed meeting and working with you and we would love to have you come back to speak at future events! 

This autumn we organized one of the biggest business events in Bulgaria – WOW Customer Service with John Tschohl. John spoke for almost 400 business owners and managers. John’s energy, passion, endurance and connection with the audience was beyond impressive. His message was relatable and his humor kept the audience’s attention for the entire presentation. From the moment he came into the hall to the moment he left the conference his focus was on our attendees and his professionalism did not go unnoticed. Our attendees left his presentation energized and excited about his message and his performance. We received a tremendous amount of positive feedback on John’s presentation!

“My name is Cleopas Chiketa I am a Deputy Director with Reserve Bank of Zimbabwe. I worked with Service Quality Institute SQI 3 Year Culture Plan . The module on Feelings for Professionals assisted our Econet Wireless Zimbabwe  team when we ran the session . It dismantled all silo mentalities and connected cross functional teams and everyone was scoped for service . The program made every staff member a front liner in their thinking as all focused on satisfying the external clients and generate value.”

Oscar M. Orozco, Senior
“During the past 16 years, my organization has utilized many of the programs that The Service Quality Institute has produced. Beginning with the original; Service First – Video Library, Leading Empowered Teams, Loyal for life and Feelings. All of them are outstanding programs to initiate a Customer Service Culture in any organization that is serious about developing a Service Strategy that will shadow its competition.

Most recently this year, we have started to train our staffs with the newest program that Mr. John Tschohl launched; Empowerment – A way of life.

The quality of this program is unequal to prior ones, in my opinion this one is one of John´s best. The excellent quality of the videos and detailed to its minute concept; Trainers Manuel and The Participants´ Handbook, is a master´s work.”

The training was held from July to September, 2015 under the theme “Feelings for Professionals” highlighting the importance of feeling and professionalism for excellent customer service.

The participants include front line employees, first line supervisors and branch managers stationed in Addis Ababa, Mekelle, Dire Dawa, Bahir Dar and Jimma. According to the participants, the training was motivating, inspiring and a true wake-up call to what customer service is all about.

The Academy thanked the instructors and their colleagues for the successful training.

This is the second time that the Academy gave such courses to trainees who are not employees of Ethiopian as part of discharging the Company’s social responsibility by sharing its best experiences in leadership and management to different public institutions and enterprises, generating revenue for itself in the process.
