Who We Are

Meet the Doctors

Paul Ettlinger

Paul Ettlinger, DC with PT privileges, is a Baltimore native who actually began his professional career not in medicine but in music, playing violin with the New World Symphony in Miami, Florida. After two years with the Symphony – and repetitive strain injuries from playing his instrument – Dr. Ettlinger turned his interests to health care and returned home to Baltimore. There, he earned a bachelor’s degree in Biology from UMBC, followed by his Doctor of Chiropractic degree from Logan College in St. Louis, Missouri. After working as an associate for several years, Dr. Ettlinger opened Health Quest in 1998.

Since then, he has received years of extensive continuing education to reinforce his clinical experience with a wide spectrum of patient conditions, including soft-tissue injuries, neuromusculoskeletal conditions, and lifestyle-related illnesses. His trademark is treating his patients as people, establishing a professional yet compassionate relationship with each. Most recently, he is completing certification as a whiplash and soft tissue injury specialist through the Whiplash Injury Biomechanics and Traumatology program at the Spine Research Institute of San Diego.

Dr. Ettlinger lives with his wife, two sons, and dogs in Pikesville and looks forward to continuing to treat the growing population in the area.

Sarah Barbee, DC with PT privileges, was born and raised in Maryland, attended the University of Maryland, Baltimore County in Catonsville, where she earned her bachelor's degree in biological sciences in 2006.

She is a licensed chiropractor with physical therapy privileges in the State of Maryland, joining Health Quest in 2015 after treating patients for five years at a practice on the other side of town.

She is also certified as a whiplash and soft tissue injury specialist through the Whiplash Injury Biomechanics and Traumatology program at the Spine Research Institute of San Diego.

Dr. Cappelletti enjoys weightlifting, tennis, and golf—basically any sport with a ball. Plus, he and his wife are active in their church and stay very busy raising eight (yes, eight) children, so he's got his hands full when he leaves the office, too!

Katharine Sparrazza

Katharine Sparrazza, DC with PT privileges, is a transplant from Rochester, New York, who earned her Bachelor of Science degree in Exercise Science and was a competitive cheerleader at the University of Buffalo.

Dr. Sparrazza moved to Baltimore in the winter of 2016 with her fiancé, who is also a chiropractor and from the area. After working as an associate for a practice in White Marsh, Dr. Sparrazza has found a better fit with Health Quest, where she can treat a wide variety of patients using the full range of her rehab expertise.

In her spare time, Dr. Sparrazza likes to work out, knit (yes, knit), travel when possible, and spend time with family and friends. She is excited about getting to know the area and becoming a strong member of the Health Quest team.

Susan DeMaille, DC with PT privileges, is a Pennsylvania native with her Bachelors Degree from the Indiana University of Pennsylvania. She began practicing more than 20 years ago after graduating with honors from New York Chiropractic College. Dr. DeMaille has over 20 years of experience working in a multidisciplinary setting - integrating care with primary care physicians, neurologists, orthopedists and other specialties. Much of that time was spent running her own practices in both New York and Frederick, Maryland, where she has been an active member of the community while raising her two sons.

Now that her boys are off to college, Dr. DeMaille has relocated back to the Baltimore area to run our White Marsh office. That includes pursuing continuing education to be a certified whiplash and soft tissue injury specialist through the Whiplash Injury Biomechanics and Traumatology program at the Spine Research Institute of San Diego. She looks forward to continue developing Health Quest's White Marsh branch and embedding herself into that part of the community as well.

Riley Barrett, DC with PT privileges, is a 2014 graduate of Palmer College of Chiropractic, Florida Campus, where he proudly earned his Doctor of Chiropractic degree with Magna Cum Laude honors. During his time at Palmer he spent uncountable hours mastering his craft through learning and practicing many of today’s most popular adjusting techniques, and developing skills and interest in the fields of rehabilitation and soft tissue therapy. Dr. Barret also holds his Bachelor’s degrees in Preventive and Rehabilitative Health Fitness and Exercise Physiology.

Dr. Barrett, his wife, and their two dogs, made the move to Baltimore, MD where he began his chiropractic career as an associate at Spector Chiropractic, the longest running chiropractic office in Maryland. Three years later, he purchased Spector's Federal Hill office and launched CHIROWORx Spine & Rehab in its place. One year later, the Barretts teamed up with Health Quest to expand opportunities around the metro area for both practices. Today, Dr. Barrett and his family currently reside in the South Baltimore Community of Locust Point, where he enjoys playing golf, watching the O’s, reading, traveling, and frequenting all of the local food and drink stops around the city.
