Cora J.
I love the policy about upfront pricing & that I didn’t have to involve myself with the confusions of insurance. Prosper Health does that for you & the price was exactly as I expected. I love that the website & portal are simple & easy to navigate. I’m glad I trusted this platform & I was not disappointed. Dr. Flor was amazing in our sessions. She opened my eyes to things I didn’t know I needed. She was aware, calm, acknowledging & her high education & training shows.

David was very good in his evaluation. Personable, very knowledgeable, and efficient. The whole interview process was pleasant. It was particularly nice that we both have backgrounds in quantitative analysis.

I had a very positive experience with Dr. Stephen Lange and the entire autism evaluation process through Prosper Health. Dr. Lange was calm, kind, and easy to talk to. He made me feel comfortable throughout the evaluation and helped me recognize patterns in my behavior and experiences that I had not fully understood before. The overall process was very straightforward, and the app was extremely user-friendly. Even someone who is not technically inclined should be able to move through the steps without difficulty. My only criticism is that the evaluation is very lengthy, but the scheduled time can still feel limited. At times, I wanted more opportunity to give context or fully explain my answers. Dr. Lange was transparent about the time constraints and let me know when we needed to keep the conversation moving, which I understood. Even with that limitation, I still felt heard and treated with respect. I have avoided seeing almost any kind of doctor since I was 15 years old, and I am now 42. I have significant trauma connected to institutions and medical settings, so completing this evaluation was a major step for me. The fact that Dr. Lange made me feel safe enough to complete the process says a great deal about his approach. Overall, the experience was professional, compassionate, organized, and validating. I am grateful for the care Dr. Lange showed me and for the clarity I gained through the evaluation.

It was so easy to navigate the website and I really appreciate the options given to find the perfect fit for my journey. I will continue to recommend Prosper Health for those on the spectrum or suspecting to be.

Insurance submission and scheduling were easy and convenient. I was able to see a therapist very quickly, the assessment process felt thorough but comfortable, and the therapist was friendly and informative. Follow-up care and referrals were readily accessible, and overall the entire experience has been great.

EDIT: After reading my report, I was surprised that it stated it was 'unclear' whether I met several criteria and that the criteria I was considered to meet were described in ways that didn't match what my loved ones had reported. I am baffled by how this conclusion was drawn. If you use Prosper, be sure to carefully read your report to make sure it accurately reflects what you discussed — or go a different route altogether. I struggled writing this review because I genuinely admire Prosper's mission of making healthcare more accessible. My provider was kind, professional, thorough, and knowledgeable, and even told me early on that they don't hand out autism diagnoses to everyone, which made me trust I would receive an honest, objective evaluation. Unfortunately, I left the process more confused than when I started. I sought a reassessment because my diagnostic history is complicated. After symptoms originally attributed to ASD almost completely resolved following treatment for another condition, my healthcare team and I began questioning whether I still met the criteria for this disorder—autism isn't something that just goes away, right? While Prosper doesn't assess for other conditions, my provider assured me they felt comfortable handling my case. My goal was never a specific diagnosis—I wanted an accurate answer. The evaluation gave me confidence. The interviews were comprehensive, I completed extensive questionnaires, and my family completed collateral forms. We reviewed each DSM-5 criterion together, and my provider frequently agreed that many of my behaviors were very consistent with the other diagnosis I have. When I said I didn't have restricted behaviors or a strong need for routines (I couldn't provide a single example), they even remarked, "I'll just check 'no' for those criteria on my end." However, the feedback appointment completely blindsided me. My therapist was equally surprised. My provider emphasized that another condition was overwhelmingly my primary challenge, described my case as "borderline" and "very difficult," yet still "felt very strongly" I met criteria for Level 1 Autism Spectrum Disorder. They also acknowledged the tremendous progress I had made, but made sure to remind me that autism never goes away. Rather than feeling validated, I felt like they were downplaying everything I had accomplished. My issue isn't that I received an answer I didn't want—if the evidence clearly supported autism, I would have accepted it. My concern is that autism is a lifelong neurodevelopmental diagnosis that I believe shouldn't be assigned lightly, especially in borderline cases. When I asked how they reached their conclusion, particularly given the limited childhood evidence, I didn't feel I received a clear explanation. The childhood evidence they referenced mainly included one instance where I preferred to look at something I was obsessed with during a school field trip and a general disinterest in engaging much with other children. Really? That's all it takes? While I struggled socially growing up, I had friends and understood facial expressions, tone of voice, and nonverbal communication. Again, many of the difficulties discussed seemed more consistent with another condition I have than an inability to understand social cues, something my provider acknowledged. I didn't have sensory sensitivities as a child, and my intense interests naturally faded over time rather than remaining lifelong. All of these points were discussed at length during the assessment. Additionally, "significant impairment" is a core diagnostic criterion for autism, yet this wasn't really explored during the feedback appointment, nor do I feel impaired enough to qualify for a diagnosis. As the saying goes, "if you have a hammer, everything looks like a nail." I don't believe my provider acted in bad faith. They were compassionate and genuinely seemed to care, which makes the outcome more confusing. If a case is truly as borderline as described, I don't understand why they didn't err on the side of caution. Why not, which is the case for many with complex cases, consider an inconclusive result, or simply acknowledge autistic traits instead of assigning a lifelong diagnosis? If you're looking for reassurance about a diagnosis you already believe fits you, perhaps this would provide the closure and validation you need. Still, I would encourage seeking assessment elsewhere, as client experiences and the quality of evaluations seem heavily dependent on the provider and vary widely regardless of the outcome. My experience left me with more doubt than clarity—the opposite of what I had hoped for.
