Dr. Heather Seaver was born and raised in Endicott, NY.  She grew up being very active in many sports, tennis, softball, and basketball to name a few.  But basketball took her to a new level where she continued to play at the collegiate level for the State University of New York at Geneseo, where she received her Bachelor’s of Science degree in Speech Pathology and Audiology.  After graduation, she spent 5 years working with K-5th graders on speech and language.   During that time, running became a big part of her life, but she began suffering from back pain that limited her motion.  With the help of chiropractic, she was able to pursue her passion for running and fitness.  Realizing the affect chiropractic had on her own life, she decided to attend Logan College of Chiropractic in Chesterfield, MO.  Dr. Seaver graduated from Logan in 2004 with her Doctorate of Chiropractic degree.  After graduation, she practiced in Saint Louis, MO, and completed course work for her ACE personal trainer certification and to become a Certified Kinesio Taping Practitioner.  Dr. Seaver has since been a part of the ProActive Chiropractic family since the end of 2008.  During this time she has worked with many athletes in and out of the office on rehabilitation, core strengthening, personal training, and athletic training for DeSoto high school.

Dr. Kristy Thomson


Dr. Kristy Thomson was born and raised in the St. Louis County area.  A couple years after attending John F. Kennedy high school, Dr. Thomson was introduced to chiropractic by an intern she met while waiting tables at Pasta House.  He and his wife became friends and asked if she would be interested in being their Chiropractic Assistant when they moved back to Albany, NY in a few months.  The thought of starting a new career and moving away was exciting, but Dr. Thomson had just met a great guy whom she knew she was going to marry.  Dr. Thomson and Tim got married 18 months later in 1987.  But the idea of being a Chiropractic Assistant interested her, so Dr. Thomson enrolled in a Chiropractic Assistance course at Logan College of Chiropractic.  In 1986, she started as an assistant in a busy office in Richmond Heights, MO.  After studying broadcasting, Tim embarked in a career in radio which brought them to Jacksonville, IL.  From 1990 – 1995, she worked as an office manager for another busy chiropractic clinic in Springfield, IL.

Being a part of two successful offices and seeing many patients achieve health and wellness through chiropractic care, Dr. Thomson, her husband, and 2-year-old daughter moved back to the St. Louis area, so she could attend St. Louis Community College to receive her Associate’s Degree in biology.  She then continued on to Logan College of Chiropractic in 1998.  She graduated in August 2001 with B.S. degree in Human Biology and a Doctorate of Chiropractic.  For the past 13 years before joining the ProActive Chiropractic family on a full-time basis in July 2018, Dr. Thomson had a part-time home visit practice in the West County area.  Dr. Thomson has been part of the ProActive Team for the past 10 years covering for the other doctors while they took time off for vacations, maternity leaves, and other emergencies.

Having a home visit practice allowed Dr. Thomson to specialize in family care.  Having 3 daughters adjusted since birth, treating children is a passion of hers.  In addition to her beautiful daughters, she has a wonderful son-in-law and a very active 1 ½-year-old puppy, Skye.  The family loves to vacation at the beach and attend Cardinal games.  The entire family is very active serving in many ministries for their church in Ballwin, MO.
