"As we discussed earlier, I'd like to have Mark Ditko teach our InRoads/SelectCAD classes whenever possible. He is by far, the best instructor for this subject matter that we've had from Bentley or Intergraph. He had a difficult class in April with students from very diverse backgrounds, but managed to present the material in a way that was interesting and helpful to all. New InRoads/SelectCAD users were able to catch on quickly and more experienced users did not feel at any time that the material was beneath their level of competency. That's no easy feat that he accomplished. Class participants have spread the word about his class and I have numerous requests that others be placed in his next course. In addition, supervisors of some of those who attended his training have also had praise for the class and the abilities shown by their personnel as they returned to production. Mark made what has been a difficult transition to Version 8 seem a lot less stressful with the information that he presented and the manner in which he presented it. Please pass my comments on to Mark and to David Fagerman. There are not many instances when I feel compelled to praise an instructor and I want to be sure that Mark gets credit for his obvious hard work."

I wanted to make sure it was known what a fantastic job Mark does!"
- Andy

"I think you are very thorough and you do your job well. I like thorough. It usually does not leave room for questions or misunderstandings. If you were single, I would marry you."
- Kimberly

I wanted to take a few moments to let you know of the excellent performance that Mark Ditko provided on our Kodak-China project. … During the various weeks that Mark was here, he provided exceptionally productive service to our project, helping us complete our design and meet our deadlines. Mark provided our staff with clear, understandable guidance in use of the different software packages. He added valuable insight to the use of the software and provided suggestions for modification of our work procedures so that we could take further advantage of the software's design and output capabilities. … Mark proved to be extremely dedicated to helping us complete our project, often staying beyond work hours to complete the design work, help us resolve a specific problem with the project design, or to resolve a problem that we were experiencing with the software. He took "personal ownership" of the design, making every attempt to make sure that the work was correct and complete. … Mark also worked very well with our staff, always positive in sometimes very stressful situations. I would not hesitate at all to have Mark return for support of this or any other project, and I would highly recommend him to others."
- Ted

"Mr. Ditko strengthened our knowledge with more efficient methods."
- Samir

"Sorry it has taken so long getting back with you expressing our thanks for the time you spent working with our Company. Also, we appreciate the time you also spent with us in the two day Inroads Training Class. All the Cad users that attended your class commented on how knowledgeable you were and the time you willingly spent with each one answering their questions. You are without a doubt one of the most informative instructors we have had from Intergraph. A lot can be said about an individual who is willing to share his knowledge with others. Hope to be working with you in the future. Sincerely,"
- Ronald

"Thank you for the excellent assistance that we at the Alabama Department of Transportation (ALDOT) have received in developing preference files for InRoads Version 8.2. Through the hard work of Pat Evans and a team of our design personnel, I understand that we now have a good set of preference files that work well with our CADD standards. As always, James Rich was available and tireless in ensuring that the support that we needed was made available to us in a timely manner. In addition, through his training duties for us, Mark Ditko was able to meet many of our InRoads users, ascertain their needs and give them insight into the capabilities available with the InRoads product and the proper setup of the preference files. The efforts of all three of these Bentley employees combined to offer support for ALDOT roadway design projects and helped to foster a satisfied use of your products. Please extend our sincere thanks to Mr. Evans, Mr. Rich and Mr. Ditko for their dedication and hard work on our behalf. We at ALDOT look forward to working with them in the future and continuing a good relationship with Bentley.
- Ivy

"I just wanted to let you know how much Parsons Transportation Group (SECC) appreciated Mark Ditko's presence in Denver last week. I use InRoads very extensively and it is rare that I meet anyone with his capabilities. It would be a tremendous advantage to have his assistance for an extended period of time on this job. Unfortunately, I am not in the position to make something like that happen. Although I did not get the chance to attend the training, Mark went out of his way 'after hours' to solve a relatively complicated problem with regards to roadway modeling and answer other questions as well." Thanks again,
- Adrian
