Owner SLS Fitness

Sherri Laffey Sarrouf

Sherri Laffey Sarrouf, the owner of SLS Fitness Strength and Conditioning Center, opened SLS Fitness six years ago in Lowell, Ma. Since that time SLS Fitness has expanded to three locations and its main facility has grown from 7,500 to 18,000 square feet which includes Group Fitness training areas, Boxing, MMA, Yoga and Metabolic Strength and Conditioning, Team Athletic Based training, Physical Therapy specialists, Chiropractic services, raw juicing and organic protein shakes, food and holistic supplements. Ms. Sarrouf pioneered the concept of ‘class based’ functional movement.  When SLS opened in 2010 the concept of having a coach in a group setting was a totally new to the fitness industry.  The establishment of a intensive ‘30 minute’ workout coupled with the tenacity to hire the best certified and educated coaches has made SLS a top strength and conditioning facility in New England.

After traveling to Wake Forest University in 2009, to train with Metabolic Effect owner Jade Teta, Ms. Sarrouf launched the first Metabolic Effect group classes in New England. Metabolic classes exploded at SLS and the demand for the class, by members, is continually increasing almost seven years later.

Ms. Sarrouf and the SLS staff was chosen to partner with Lowell General Hospital to be their public educator offering seminars on the importance of fitness.

Prior to founding SLS Fitness Ms. Sarrouf’s experience in the strength and conditioning industry spanned 27 years throughout Massachusetts and New Hampshire. Officially incorporated 12 years ago, under the corporate banner of Elite Fitness Professionals, Inc., Ms. Sarrouf provided group fitness management for Gold’s Gyms in Nashua, NH,  Merrimack, NH, Manchester, NH and in Tewksbury, MA.

Sherri Sarrouf is also the founder of the Fitness For a Cure fundraiser to benefit ALSAC/St. Jude Children’s Research Hospital in Memphis TN. Fitness For a Cure has raised 3.6 million dollars for St. Jude Children’s Research Hospital since its inception 18 years ago. What began as a $5,000 event in 1999 has grown to a $450,000 annual event supported by a committee of 100+ volunteers and the Lowell community. She has traveled throughout New England speaking to numerous groups, businesses and schools on behalf of St. Jude and was a 2016 finalist nominee for the prestigious Enterprise Bank Philanthropic Award for her work and dedication for St. Jude.
