I was referred to Dimensions by someone in our building. I have had the privilege of working with Ali for a few years and then with Lisette for a few more years. I knew I needed help when I became nervous about my balance. Having scoliosis complicates my exercise routine and Ali works with me with knowledge and understanding of my condition. Each session is slightly different and his personality makes the time go by very quickly. After only 4 months or so, I felt stronger and more confident and my posture has improved. I would heartily recommend the company to anyone seeking a great personal trainer.
