20170411_084911_001Tiffany M. Wolf, PT, DPT: Tiffany is a Colorado native, born and raised in the Denver metro area. While in high school, she discovered a love for sports and fitness, especially in the weight room. Knowing she wanted to pursue a career in the healthcare field, Tiffany realized that physical therapy comprised the ideal balance between patient interaction and her love of all things sports- and gym-related.

Tiffany attended the University of Colorado at Boulder, graduating in 2003 with her bachelor’s degree in Kinesiology and Psychology. While at CU-Boulder, Tiffany received her certification as a group fitness instructor and still teaches to this day. She then attended Regis University for Physical Therapy school and graduated in 2006 with her Doctor of Physical Therapy degree. Following graduation, Tiffany moved with her husband to northern Nevada where she practiced in multiple settings including acute care, acute rehab, home health, and (her favorite!) outpatient orthopedics.

Both Tiffany and her husband are from close-knit families, so they decided to move back to Colorado in 2011 after starting a family of their own. Since returning, Tiffany has been working exclusively in outpatient orthopedics. With her strong fitness background and years of diverse experience, she believes that therapy is a team effort between patient, therapist, doctor, and other health care providers. Tiffany is a firm believer that physical therapists are the musculoskeletal specialists and, as such, her goal is to give patients the tools to succeed both immediately in rehab as well as in future fitness programs.

Tiffany is currently working towards her Manual Therapy Certification through the University of St. Augustine, and is certified in Dry Needling through the Dry Needling Institute. Away from work, Tiffany enjoys running, triathlons, aerobics, and spending time with her husband, two young girls, and two dogs.


Miguel feb13

Miguel Guzmán, Bookkeeper:  Miguel is a Mathematics and Business Administration graduate from Saint Francis College in Biddeford, ME. Born in Puerto Rico but has lived most of his life in Colorado. He recently joined our staff family and is a fabulous person to work with. His sense of humor and wit is constantly interfering with our work. So when you call and no one answers the phone, it’s because we’re rolling on the floor with laughter. Among his other interests: he loves to travel to far away and exotic places, photography (at which he’s is getting better), cooking and fortunately burning calories at the gym.
