The overall experience at LifeStance Health's Kissimmee location is generally positive, with most patients expressing satisfaction with the quality of care and the kindness of the staff. However, there are some inconsistencies and areas for improvement. Some patients have reported issues with appointment scheduling, communication with providers, and billing. One patient had a particularly negative experience with a provider who was dismissive and unprofessional. On the other hand, many patients have raved about their therapists, particularly Mercedes Gibbons, who is described as knowledgeable, caring, and professional. The online appointment system is convenient, and many patients appreciate the flexibility of telehealth services. However, there are some concerns about the cost and insurance coverage, with one patient reporting being overcharged for services. Overall, while LifeStance Health has some strengths, it also has areas for improvement in terms of communication, billing, and staff consistency.
