About Us

Powerhouse Training was built on the premise that training results depend heavily on both coaches and the facility/equipment. Purchasing unique equipment and training tools that can’t be found at nearly any other gym in the country in addition to having the areas only indoor/outdoor training set-up was a quick and relatively easy process.  Getting elite level coaches with the background, education, and ability to communicate their knowledge effectively was more challenging. After 9 years in the field, I feel our staff can rival almost any facility in the country – just like our equipment and facility. Our results have been a direct reflection of the quality of coaching we have.

We don’t just pick and choose elite athletes to train. We choose to DEVELOP them.

Here is a glimpse of some highlights from our instructor’s bios.


*We have 4 CSCS (Certified Strength & Conditioning Coaches from the NSCA) and 1 ISSA certified coach.

*We have 4 full time former professional players on staff for baseball instruction.

*We have 2 former Major League players available for lessons/consultations part time.

*We have 3 former professional pitchers who officially threw 90 mph + in games.

*We have 3 instructors with college coaching backgrounds and one who coaches Team USA – women’s program.

*We have two MLB scouts on staff.

*Together we have worked with thousands of athletes. We have developed 8 professional baseball players, one NFL signee, and worked with countless others. We have developed 13 All-Americans at the high school and collegiate level in 4 different sports. We have sent close to 150 athletes on to play collegiate athletics, with numerous players earning scholarships to top 25 Division I programs.


When athletes walk into our facility they can rest assured we have the experience and expertise to help them meet their goals.

Here is a glimpse of just a few of the schools where we have helped send players. (Right now we have well over 150 athletes who went on to play collegiate athletics).

Jon Davis, together with Chris Ott, founded Powerhouse Training in 2010. Davis, a former professional pitcher, made a name for himself as being on the cutting edge when it comes to developing training programs and methods for producing dramatically stronger, faster and more explosive athletes. Davis was on the forefront of the development and implementation of over-underload training for athletes, a method he began using in 2000. Davis had an article published in 2006 on overload-underload training that went on to become one of the top searched and referenced articles relating to implementation of overload-underload training into baseball and softball. The method is referenced and used by numerous professional coaches and has resulted in countless products being developed based on the info in order to produce faster throwing speeds and bat speeds. In 2015 alone Davis had 10 local athletes break the 90 mph throwing mark after using the unique training method/program.   Jon also has the distinction of training 8 different high school players from the Western Massachusetts area who went on to sign professional baseball contracts by the time their high school/collegiate careers ended.


Jon’s creative programming and training methods have helped produce over 100 All-Western Massachusetts high school All-stars, 13 All-Americans at the High School and Collegiate levels, and 3 Western Massachusetts Player of the Year (football, baseball, girls lacrosse).   He has helped train/develop over 120 athletes who went on to play collegiate athletics, with many of those athletes earning scholarships to top of the line D1 schools. In 2014 and 2015 Davis helped produce back to back top 10 round MLB draft picks (position players) out of the high school ranks for the first time in WMASS history (Isan Diaz and Seamus Curran). Both players continue to train regularly at Powerhouse.


Davis graduated magna cum laude from Springfield College in 2006 with a degree in Applied Exercise Science. He has been CSCS (Certified Strength and Conditioning Specialist) since 2007. Jon is a strong believer in practicing what he preaches. He feels strongly that a coach should be able to demonstrate and represent what they teach to their athletes. Jon is the Massachusetts state Powerlifting Chairman for 100% Raw Powerlifting. The federation is a drug free equipment free federation.


Playing Background

As a player Jon starred at Cathedral HS in Springfield where he accumulated 25 wins and 310 strikeouts while leading his team to 3 straight WMASS div 1 finals appearances, 2 WMASS championships, and 1 state finals appearance, while garnering player of the year honors in 2002.  Davis went on to play his college ball under Mark Simeone at Springfield College, earning 2nd team All-New Mac conference during 05 and 06 while producing a 1.93 ERA as a senior with opponents hitting only .157 against him.  Jon also played 2 summers in the prestigious NECBL where he was one of the league’s top closers in 2005, producing a 1.00 ERA with 7 saves.  He defied the odds as a 5’9” RHP by earning a professional baseball contract as the only player to sign out of the 2007 tryout sponsored by the New Haven Cutters and Pro Dreams. The tryout consisted of well over 100 players from all over the country. His low 90’s fastball at 5’9” 170 lbs was a product of his unique training methods that he now teaches to his athletes.

In addition to playing professional baseball Jon has assisted in the training and development of

Moyers bio here






Garrett Baker, an East Longmeadow native, joins Powerhouse Training after recently graduating with his BS in Exercise Science from Cedarville University in Ohio. During his college tenure, Garrett interned at Powerhouse Training and worked training athletes at Enhance-U, a sports performance training facility in Ohio. Last year, Garrett served as the 18U Dream Bats’ pitching coach. From 2009 through 2012, he also volunteered as a pitching coach for three AABC youth state championship teams.


As a player, Garrett was a three-year letter earner who helped to lead East Longmeadow to several league titles and three Western Massachusetts Division 1 final appearances. Garrett earned second team and then first team All-Scholastic Western Massachusetts distinctions during his junior and senior years.   During his senior year, he was named captain as he earned a 1.39 ERA with 70 Ks in 45.1 innings.   The following year, he attended DII Cedarville University on a baseball scholarship. As a four-year starter, Garrett made an immediate impact. He became a weekend starter his sophomore year, and he was named the opening day starter and ace at the beginning of his junior year. Unfortunately, Garrett had season-ending Tommy John surgery early that same year. During his rehabilitation, Garrett turned to Jon Davis for his training and mechanical adjustments. As a result of Jon’s help, Garrett entered his senior year increasing his velocity from 87-88 mph to 89-91 mph. Garrett once again was named opening day starter and the team’s ace. His senior year’s ERA was 2.54 with 68 Ks in 60.1 innings. He was named player of the week multiple times, and he achieved first team all-conference, while also distinguishing himself in many conference-pitching categories. Post-graduation, he began his professional independent baseball career by being contracted to pitch in the starting rotation of the Empire League’s New Hampshire Wild.



“I’ve been fortunate to have been able to consult and learn from some of the top minds in the field for baseball and performance training. I honestly can’t think of someone who is more well versed in the mechanics and training of pitchers and baseball players than Garrett. I make it a point to sit down with Garrett on a regular basis to discuss ideas on how to most effectively train pitchers. It’s a unique situation, as I feel I learn as much from Garrett as he learns from me. I couldn’t be more excited to have him here at Powerhouse going forward. Garrett is a gifted coach who studies the game like no one else I have come across. He has also walked the walk as a player, as he overcame Tommy John surgery and watched his fastball climb into the low 90’s. In addition he is a current professional pitcher. There aren’t many people who can match that type of resume!”

Corey was drafted by the Red Sox in the 2011 MLB Amateur Draft. Corey overcame incredible adversity to get to that point. Corey and his two brothers were orphaned in 2005 when their mother passed away suddenly.   Through the tough times and adversity Corey managed to persevere, heading up to Division 3 Keene College to play baseball. Again defying the odds, Corey managed to get drafted by the Red Sox after putting up outstanding numbers in college and the prestigious NECBL to compliment his consistently 90+ mph fastball. Like Powerhouse owner, Jon Davis, Corey went from playing division III College baseball into the professional ranks.


“We are incredibility lucky to have Corey on board with us here at Powerhouse. His playing background combined with what he can teach these kids about never giving up and overcoming adversity is second to none. Corey has a tremendous knowledge of mechanics and pitching. He has walked the walk as a player and coach, too. (Pitching coach at American International College after finishing playing career) Unfortunately, it’s become increasingly popular for instructors to fabricate stories about how hard they threw or claiming to play at a high level to attract clients. Corey really does have the background. In fact, one of the first days I saw him I witnessed Corey take a ball and step on a mound with ZERO warm-ups and hit 89. Several days later I watched him hit 94 mph on the stalker radar gun despite being out of baseball for several years!”

-Jon Davis










Raul Diaz was the best kept secret in the area for a long time. He has an incredible passion for teaching and mentoring young players and passing on amazing baseball knowledge. Raul began coaching and working with friends and family for free in order to teach the game the right way. In the process, Raul saw his son Isan become the highest drafted high school position player in Western Mass. history (2nd round MLB draft pick). People saw the incredible passion, intensity and love for coaching Raul brought to the table and within his first year of working at Powerhouse, resulting in his schedule booking solid in under a years time.

Raul has received glowing recommendations from players and parents of all ages and ability levels. Raul’s schedule books solid from the October – April time frame. It is highly recommended to call well in advance when looking for lessons during the winter time frame.


“Raul Diaz has a gift for coaching and teaching the game that is rarely seen. I have had the pleasure of working with and watching some of the best coaches in the area over the past 10 years and I can’t recall someone who cared more for the kids then Raul Diaz. On the outside Raul is as tough as they come but deep down you can see how much he cares for the kids and provides a positive role model. In the process he squeaks every ounce of talent out of the players he works with. Be prepared to sweat and work like never before when you step in to work with Raul!”

Doug Clark has one of the most decorated professional careers of any Western Ma player in recent history. He has a 20-year professional career in which he held a .296 batting average while displaying tremendous power and speed. He played in the MLB with the San Francisco Giants and Oakland Athletics. His MLB career was somewhat limited as he played behind one of the greatest players in history (Barry Bonds). Clark excelled at every minor league level including starring in Mexico and Korea. He is currently a minor league coach during the Spring and Summer.


Clark actually was a star high-school football, basketball and tennis player at Springfield Central High School in Springfield, Massachusetts. He would attend the University of Massachusetts Amherst on a football scholorship as a wide receiver. However, Clark would walk on to the baseball team, and in three seasons post a career batting average of .366 with 21 home runs, 137 RBI, and 49 stolen bases. Clark would be drafted by the Milwaukee Brewers in the 20th round of the MLB Draft following his sophomore season, but would return for his junior year. Following that season, he was picked in the 7th round of the 1998 MLB Draft by the San Francisco Giants.


Clark would sign with the Giants in 1998 and was assigned to the Single A Salem-Keizer Volcanoes of the Northwest League. He would spend the majority of the 1999 season at Single A Bakersfield and had a successful stint with them, batting .326 with 11 home runs, 58 RBI and 17 stolen bases. He would also play 15 games with the Double A Shreveport Captains. Clark would spend the entire 2000 as well as 2001 seasons in Shreveport. He enjoyed two fairly successful seasons hitting .272 with 10 home runs and 75 RBI in 2000 and .275 with 6 home runs, 51 RBI and 20 stolen bases in 2001. In 2002 Clark started the season again with the Double A Shreveport Captains before being called up to the Triple A Fresno Grizzlies. He would also spend 2003 between Double A and Triple A, however, this time with new Double A affiliate of the Giants, the Norwich Navigators. Clark would play the entire 2004 season in Norwich, batting .292 with 4 home runs and 49 RBI.

Clark started the 2005 season with the Triple A Fresno Grizzlies. He played in 127 games with the Grizzlies batting .316 with 13 home runs and 59 RBI. On September 14, 2005 Clark made his major league debut with the Giants. Clark appeared in 8 games with San Francisco mainly as a pinch hitter or runner or defensive replacement. He did not record a hit but scored two runs. At the end of the season he was granted free agency by the Giants and was quickly signed to a free agent contract by the Oakland A’s Clark started the 2006 season with the Triple A Sacramento River Cats but was called up to the A’s and made his first appearance with them on June 20, 2006. Clark would appear in 6 games as a pinch hitter and would record his first major league hit. He was then recalled to Sacramento where he finished the season hitting .287 with 15 home runs and 67 RBI. At the end of the 2006 season Clark was again granted free agency and was signed by the Atlanta Braves. He attempted to make the major league roster in spring training, although he batted .429 in spring training he failed to secure a roster spot and was sent to the Triple A Richmond Braves. Clark played in 134 games with Richmond and hit .275 with 15 home runs and 69 RBI.


At the end of the 2007 season Clark was released by the Braves. However, during the 2007 season prior to a game in Richmond, Clark was introduced to a Korean scout who was in attendance and stated that he liked the way that Clark played.[1] Prior to the 2008 season Clark signed on with the Hanwha Eagles of the Korean Professional League. That season Clark hit 23 home runs with 80 RBI and 23 stolen bases, and was an All-Star. However, a midseason knee injury caused his average to drop from .315 to .250. In 2009 Clark signed and played with the Heroes but was released from the team in July 2010.

After leaving the Korean league, Clark again shopped his talents to the baseball world and was signed by the Mexican League team Tigres de Quintana Roo for the 2011 season. At the end of the regular season Clark was the team’s starting left fielder and was the second leader of them in batting average .315, on-base percentage.423, and slugging percentage .579.
