Sal has been a phenomenal leader and coach. Always willing to get into the trenches and leaves no stone unturned. Sal’s thoughtfulness and customer driven approach turns insights into action. Together we were able to accomplish revenue targets that seemed impossible, but with his guidance I was able to surpass goals. What I love about working with Sal is that he’s not afraid to give constructive feedback, meaning that he truly cares about the professional development of his team. He’s also an all around great person and always shows up with a positive attitude and ready to take on any challenge. Cheers to working together!

I had the pleasure of working alongside Sal during his time at Yelp. While I didn’t report to him directly, his leadership had a clear and positive impact across the team. Sal is an exceptional leader—motivating, approachable, and always willing to lend a hand. He fosters a culture of accountability and positivity, and it’s clear that people genuinely enjoy working with him. Sal’s sales acumen is equally impressive. He has a strong grasp of strategy and execution, and he knows how to drive results while developing those around him. Whether coaching reps through deals or identifying ways to improve performance, he brings both insight and action. Above all, Sal leads with professionalism, integrity, and heart.

Mark Kronenberg does an excellent job. My son, Ethan, was learning remotely from Amity High School in Woodbridge during Covid. It was his last semester in high school. Needless to say, the school had no plan in place during those first few months and there was no active teaching program in place. Not only was he remote, but he also had to complete a semester's worth of assignments with NO instruction. He was taking Calculus 2 and it was rough. We hired Mark and in 2.5 hours he taught Ethan a month's worth of Calculus. He passed the class and graduated from high school. I can't say enough about Mark's passion for Mathematics and making it very relatable to the students.

Mark was a perfect match for my daughter and within a few weeks I saw a noticeable gain in my daughter's skill and confidence. Thanks again for your help.

Mark has a thorough understanding of math and imparts that knowledge succinctly to my daughter. I am truly appreciate as a parent.

Mark is punctual, organized, and always well prepared. He is willing to work with our child's teacher directly, and adapts to varying needs. Most importantly, he is supportive, direct, and sets a standard that acknowledges the motivation and capabilities of our child, while simultaneously maintaining good rapport with the child and parents.

He is punctual, patient, and knowledgeable. He has taught both of our children, removing our daughter's initial fear of math and our son's tendency toward carelessness. Both of our children benefitted significantly from their time spent with Mark.

For the past semester, Mark has been tutoring our daughter in ninth grade math. We have found him to be excellent. He understands the concepts, is able to guide our daughter toward the specific goals set by her school's curriculum, and as a result has helped her to elevate her test scores.

I want to thank Mark for helping my son. John is 16 years old and a junior in high school. He has always struggled with math. In his freshman year, John had to take the Math Regents. We said to ourselves "No way will he pass." The tutor worked with John once a week. John passed the Regents. We continue to call whenever John needs help.

I tried to get referrals from teachers, friends, and friends who are teachers. Most didn't have a clear suggestion on where I could get help as my kids began to struggle with math. Jane was shy and hated going in after school to ask for help. My enthusiasm waned. To help, I went online to do some reading and checking and found Mark. It was a marvel. In just one session, Jane not only had the concepts down, but they'd figured out where she got lost so she could catch up.
