Had a very fantastic time here at Quest, every staff member was kind and considerate including but not limited to Donny (head of staff), Lynn, Aureli, Angela, Keisha, Geo, Arthur, all the nurses and therapists (Kelly) who took the time to share her inspiring experiences with me, Coach J who taught me that real bread only has 3 ingredients, and the chef Tasha who cooked absolutely amazing and healthy meals and also took the time to give us meal plans for when we departed. She even let us barbecue, under supervision ofc. We also recorded music weekly with Danny which was always fun, he’s very talented. There was also a lady who came in a played some sort of therapeutic bowl that put me into a deep sleep almost everytime she stopped by. When I got the call from the recruiter (Dustin) I immediately wanted to believe that I could take a trip to Cali to a mental health retreat but my family, understandably so, had reservations. You know what they say about things being too good to be true. I was set to leave that Sunday from nyc to Cali, and it was Friday. Dustin helped assuage our concerns but my family still had some doubts about the billing, insurance, lodging and programs. I end up speaking with Marina (co-founder of the program) and Armen the other co-founder who wrote me a letter to guarantee that if my insurance decided that they wouldn’t cover the treatment after I arrived, that I would not be personally liable. And true to their word, my insurance covered the entire payment (a very large amount- I stayed 35 days). The other clients I got along with well and still speak with my roommate and others to this day. (One roommate btw, so not so bad), tv bathroom in the room(not all the rooms had this setup). Spacious McMansion, basketball half court in the backyard along with a minigolf (which I didn’t use but looked cool definitely). Hot tub and pool that lit up. Gym which I also used a bunch. Oh I forgot to mention there are different houses with different setups so the house you experience might not be the same as the one I’m describing. The other one I visited was nice as well. We went on plenty outings weekdays more local like desserts, fast foods like in n out and the smoke shop. Weekends we went to the beach sometimes, the movies, an observatory in the hills overlooking the valley etc… Best of all I haven’t even mentioned my mental health which indeed did make a big recovery and trust me, I had a lot of problems. I’m not saying I’m totally cured, but I’m definitely better. Thank you Quest Health, you run a fantastic program that’s actually helping people.

Beautiful house is absolutely immaculate and they have a great pool in the back! Quest Behavioral Health truly stands out as a truly amazing mental health program. From the moment you walk in, there’s a sense of calm, structure, and professionalism that immediately builds trust. What impressed me most is their trauma informed clinical approach. This isn’t a surface-level program they take the time to understand the root causes behind depression, anxiety, and mood disorders, and build individualized treatment plans that actually address those underlying issues. The use of evidence-based therapies like EMDR, combined with consistent individual and group sessions, creates a well-rounded and effective clinical experience. The staff is exceptional knowledgeable, present, and genuinely invested in each client’s progress. You can tell there’s a strong culture of care and accountability, which makes a huge difference in outcomes. Clients aren’t just monitored here they’re actively engaged and supported every step of the way. The environment is clean, comfortable, and thoughtfully designed to feel safe without being clinical or institutional. It’s a setting where people can truly focus on healing. If you or a loved one is looking for a program that combines clinical depth, personalized care and a strong path towards long term stability. Quest Behavioral Health is an excellent choice. Highly recommend

As a parent, trusting someone with your child’s care isn’t easy, but Quest Behavioral Health truly made a difference for our daughter. We’re incredibly thankful to the entire staff for the care, compassion, and support they showed her every step of the way. They created a safe, structured environment and kept us involved throughout. We’ve seen a real change in her. She’s happier, more emotionally stable, and more like herself again. It finally feels like she’s herself again. We’re truly grateful to the entire team for everything they’ve done. We would highly recommend them.

My son was here for help and I was pleased with how they took care of him, helped him and assisted him in filling out work forms, school forms, disability etc. Donnie was very efficient at staying on top of these details that needed attention. Thank you all for your help.

I arrived and I was in a really dark place, I needed help in the worst way. Well the staff at Quest are really there for you. They were awesome and so supportive. I followed their guidance and slowly but surely I found myself again. Today I am holding my boundaries, I am active and social. I am so glad I asked for help and went to Quest. I highly recommend this place.

Frequently Asked Questions

Choosing mental health treatment in Lancaster often comes with important questions. Here are answers to some of the most common questions about getting started at Quest Behavioral Health.

How do I know if mental health treatment is right for me?

Residential mental health treatment may be the right choice if your symptoms are affecting your daily life, relationships, or ability to function safely. It provides a structured, supportive environment with around-the-clock care, individualized therapy, psychiatric services, and ongoing clinical support. Our admissions team will help determine whether residential treatment is the most appropriate level of care for your needs.

We provide personalized care for depression, anxiety, trauma-related conditions, bipolar disorder, dual diagnosis, and other behavioral health concerns. Every treatment plan is tailored to your unique symptoms, goals, and personal history using evidence-based therapies and a whole-person approach to care.

Yes. We work with most major PPO insurance plans and offer confidential insurance verification before treatment begins. Our admissions team can explain your available benefits, answer your questions, and help make the admissions process as simple and stress-free as possible.

Healing continues after residential care. Before you complete treatment, we develop a personalized aftercare plan that may include continued therapy, psychiatric follow-up, community resources, and other recommendations to help you maintain your progress and support long-term wellness.

Getting started begins with a confidential conversation with our admissions team. We’ll listen to your concerns, answer your questions, verify your insurance benefits, and help you understand the next steps toward receiving personalized mental health treatment.
