Krista is awesome. She's very professional but also leaves room to be silly and to have a good time while learning! We've covered so much in such a small amount of time and I'm really happy with my progress.

Krista took the time to learn what my level was and changed her teaching methods effortlessly to accommodate not only my level but also my learning style. Can't wait for the next lesson!

Has been an excellent experience for my 14 year old daughter. We'd tried out two other instructors previously, but Krista was a better fit all around. My daughter looked forward to her lessons and was fully engaged during them. Krista had great communication, an easy manner, and crammed a lot of knowledge into each lesson.

Great instructor! She was very receptive to my questions and requests on what to learn next. Has some intriguing insight on certain signs. She also made me feel very confident in my learning! I look forward to my next lesson with her!

Krista and I agreed on 30 minute lessons every week in august and yet the reciepts for my lessons that we recieved in december, say that we have been charged for hour long lessons the entire time. The lessons only lasted 30 minutes and she would always day goodbye after 25 minutes. When I tried to talk with her about this discrepancy she refused to resolve it and I was left feeling that she had been dishonest eith me. Indo not recommend taking lessons with her. I am very sorry to write this but it was truly and awful experience and I hope it doesnt happen to anyone else.

We have had the privilege of taking 9 classes with Krista and we can already communicate in sentences. She is very patient, willing to repeat, great at explaining how to form a sign and very encouraging. Krista will adjust the lesson to where you are without judgement. It is evident she has a lot of experince and is passoinate about her teaching. We look forward to every lesson. We would highly recommend Krista if you are interested in learning ASL!

Great Lesson!

I really enjoyed my lesson. She was able to find what level I am and build from there, since I've already have a little bit of knowledge in ASL. She was very helpful in teaching me new signs that I would use in my work environment and how to use in the correct way. I look forward to the next lesson!"

Today was my first ASL lesson with Krista. I can't wait to see how it goes on my next session. She has patience for people that have no experience with ASL.

I had to learn a lot of topics in a very short time. She helped me accomplish this by having great conversations using all the vocab she has taught me. She is a great teacher and I recommend her to everyone.

Krista's professionalism and personal attention to detail shined through as I learned American Sign Language. She has a deep love for the language and provides individual personal attention to make sure you learn the most during each lesson while having a lot of fun. I would recommend her whether you have a child wanting or needing to learn or for yourself as a beginner, intermediate or advanced language learner in ASL. Thank you Krista for a great experience!

Krista has been patient and encouraging. We have skyped for our lessons and she is very reliable. She has never changed times or forgotten a lesson. She is happy to teach me whatever I am wanting to learn and provides examples for what we discuss. I am learning much from her and am enjoying the experience.

I've been tutoring with her for a few weeks now, and I have to say she is a great tutor! She is very patient and accommodating, and when I struggle with a certain vocabulary term, she is there to break down each motion of the sign to help me understand what the motions are. My grades have improved and I am very grateful that I found such an awesome tutor.

Having Krista as my tutor was one of the best decisions I ever made. Krista is impeccable in the way she prepares you to be successful, she points out the little pitfalls you might encounter so you're not surprised if and when you're faced with any difficulty during the lesson. I've found Krista to be a very positive and nurturing teacher, who sincerely cares about her students. Because of my positive experience with Krista, I look forward to further success in my studies.

"I took sign language courses about a year and a half ago. I decided to take up the language because I have an uncle who is deaf. I took private classes from the comfort of my home via skype. Krista was my teacher and she was absolutely amazing. We worked together to meet my goals. I would not hesitate to take courses again. I definately recommend classes to anyone interested. It is very important to learn sign language especially if you work for the community. I am a teacher and my students love that I can teach them signs.
Krista and I made a plan of what I needed to know, as well as things that I wanted to know. She is a great instructor and the company is fabulous! "

"Good Evening-

I would like to provide some feedback:

My tutoring session was with Krista Duffy. I am more than pleased with her assistance. Krista has a very positive attitude and great energy. She was completely attentive to what I needed even though I was slightly ill-prepared for our first session. However, with her help, I realised what I need assistance with and will have another great session next time. She made me feel completely comfortable and gave me a renewed confidence with using Sign Language. Her signs are very clear and spot-on. I appreciate the fact that she has a formal education in Sign Language as well. I am grateful that she has knowledge of Deaf Culture that I can actually use in everyday existence and put to good use. I will continue to use her services as I book more sessions as soon as I am done writing this email!

Thank you for providing such a valuable resource,"
Keith Heerey
