What Our Patients Say

After my psychiatrist of more than 15 years had to stop practicing suddenly, I reached out to Lemon-Aid Medical Management. Thankfully, the treatment that I received from Dr. Jason, Dr. Candace, and their amazing team surpassed ALL of my expectations. They immediately assured me that they would be happy to help me with my medications and treatment. As a long term sufferer of anxiety, I immediately felt so much relief and gratitude that I had found the right people.. They go "above and beyond" to answer any and all questions you may have and are dedicated to making sure that they provide you with top notch service. I HIGHLY RECOMMEND them to anyone struggling with substance abuse issues, anxiety, depression, or any other psychological issues in your life. They are the BEST and they genuinely CARE about you as their patient.

I've been a patient here for nearly 20 years. Great doctors, NP's and PA's. Their office manager Chelsea, is the best.

Dr. Jason is outstanding. He's knowledgeable, patient, and takes the time to actually listen, explain things clearly, and then come up with actual solutions. What really sets him apart is his accessibility — he's reachable directly, not funneled through an online only booking portal or endless phone trees. That kind of responsiveness is practically unheard of in healthcare today. His staff is also incredible. I'm so glad I made the switch to him as my Primary Care Physician. It's been life changing.

They saved my life! Dr. Demattia and Nurse Chelsea got me transitioned from an LVAD to a heart transplant in a timeframe that I never felt possible!!! Their care and overall support for myself and my wife will never be forgotten! At 49 I've seen plenty of doctors in my life but never have I had a team of nurses and doctors that fulfill role with such direction and compassion. Even checking on me several times in the ICU after transplant. Lemon-aide is just as sweet as the name! Thank you Dr's Demattia I'm forever indebted! Happy New Year! Happy New Heart!
