About

I have a unique professional resume which combines a successful major league baseball career with a master’s degree in sport psychology and counseling from Boston University. Despite two arm surgeries and several demotions back to the minors, I persevered going on to win 110 games and make an All-Star team. After retiring from baseball, I returned to college to complete my bachelors degree, and three years later completed my masters degree from BU.

I have worked as a mental skills coach for three of MLB’s storied franchises and some of the games best players including; Jon Lester, Rich Hill, Andrew Miller and Anthony Rizzo, among others.

I have provided mental skills training to a number of colleges such as Tufts Men’s Ice Hockey, Boston College Baseball, Boston College Basketball, Middlebury College Baseball, Bates College Baseball, Wheaton College Women’s Lacrosse, and Eastern Kentucky University Baseball. I also have a number of individual college and high school athletes from various sports across the country.

I am a member of the Applied Association of Sport Psychology (AASP) as well as a Certified Mental Performance Consultant. (CMPC) and is trained in the DISC Athlete Assessment

“The work that Bob has done with my teams at Bates and Middlebury College has been transformational. He communicates the important concepts of the mental side of the game and introduces ways in which players can develop their own mental skills routines as players. His work with my teams has benefitted them on the field, but more importantly, has helped them to see how to connect these skills to their personal lives so they can grow as people.”

– Mike Leonard Middlebury College Baseball Coach

CAREER

After completing his master’s degree from BU in 2004, Bob was hired by the Boston Red Sox to develop the mental skills program at the minor league levels of the organization. During the next ten years the Red Sox minor leagues developed several prominent players who would help the Red Sox win the World Series in 2007 and 2013 and 2018.

On the mound, Bob didn’t have an easy path to 110 major league wins. He overcame two surgeries to his pitching arm; elbow and shoulder, as well as six demotions to the minor leagues. However, Bob’s resiliency helped him become a member of the 1992 National League All-Star team in addition to a Major League All-Star team which toured Japan after the 1992 season.

WHAT PEOPLE ARE SAYING

“On our way back to IL from ATL we listened to 90%. I saw Will pull out his phone and start taking notes. He then began to hit the pause button to finish his note as not to miss anything that was to come. I asked him what were some things that he got from his first run with this book. He said the “Little Man”, the “Stop Sign”, “Breathe”, and “Anchor Statements; specifically the Boat & Anchor analogy”. Mr. Tewks is doing incredible work and I saw it with my son Will. It has been the single best development piece of Will’s 14U season.”

“Tewks talked about different things as far as the mental side of the game, and building that relationship with him I had a trust where I could go and bounce things off of him. He’s a no BS guy. I knew he wouldn’t pussyfoot around with me. I knew if I asked him a question, he would give me an honest answer, both on the pitching side and on the mental side. I knew I would get that from him.”

– retired MLB pitcher Jon Lester

“Having worked with Tewks as a player as well as a coach, I’ve been lucky enough to see firsthand how much he can impact individuals and teams. He has been invaluable to me personally throughout my career, as well as our baseball team at Boston College.”

- Mike Gambino Head Coach Boston College Baseball

Inviting Bob to Novo Nordisk to share his unique perspective on building and utilizing mental skills to deal with failure, pressure, negativity and anxiety was a great fit for our group. His techniques and skills are applicable in any field or walk of life for which my group is better for after spending a day with Bob. I highly recommend Bob if you are looking for a presenter to inspire and teach your group.

With Tewks I have been able to improve my confidence and emotional steadiness from game to game, both of which are huge for performance. It has been like a weight lifted off my shoulders.

– Catcher UNC Greensboro

I loved how relatable Tewks was. It was nice to know that as a former professional player, he went through these same struggles as well. It was nice to know that I was receiving advice from a ballplayer.

– High School baseball/ football player

Tewks helped me work through my fears and how to talk myself through them when I was pitching

– Minor League baseball pitcher

Before working with Tewks, I easily lost control of my mind and body while on the pitching mound in tight situations. Working through my mental weaknesses and working our strategies to control my brain while in game led me to having a dominant summer and changing the tempo of my game.

– High School baseball player

I am actually in a really good spot right now, largely thanks to the practices that you have given me through mindfulness, journaling, and anchor phrases.

– retired MLB pitcher Jon Lester

“He tells you what he sees, and he calls you out on things. He makes you better as a player as you go along. The biggest thing I’ve found is that if a player continues to seek advice, seek help, there are people who can help that player get the most out of his potential on the baseball field.”

- Rich Hill, MLB Pitcher

“I’ve worked with other people, but the stuff we put in place in Boston is what I’m still using today,” Miller says. “It’s a very important part of my success, or turnaround. It’s something I take very seriously and I think it’s had a big impact on my pitching.”

- Andrew Miller- MLB Pitcher
