About Us

Westside’s Mission

Our mission is to facilitate a timely gateway to outpatient, mental health services. We make it easy for people in our community to use their insurance benefits to access exceptional therapists in private practice.


Our scheduling process features our proprietary Search-and-Schedule calendar app, which matches clients with available therapists who actually meet clients’ needs. Matching factors include therapist availability, insurance coverage, specialty, client age, location (for in-person sessions), telemedicine (for sessions online), time of day, and day of week. Unlike other companies who work with therapists in private practice, our app schedules real appointments: long gone are the days of submitting an appointment request or leaving a series of voicemails hoping one of a dozen providers gets back to you. At our core, we believe that finding the right provider and scheduling an appointment as soon as possible increases client outcomes and satisfaction. Our client satisfaction rating is 4.5 out of 5.

Our team works tirelessly to match people seeking care with providers actively accepting new clients. We are constantly improving our website, simplifying our scheduling software, building relationships with partners, and empowering providers to establish and grow their private practices.

For those who prefer a more personal touch, our scheduling team provides one-on-one assistance over the phone and by email. For those who prefer efficiency and convenience, the Schedule Online tab on our website shows up-to-date provider availability and allows visitors to self-schedule appointments in as little as 5 minutes. To make both approaches as effective as possible, our team is typically able to respond to incoming questions on the same day.

Patient Values

  • ALL ARE WELCOME. We seek diversity. We encourage creative thinking. We thrive on flexibility. We assume good intentions. But most of all, we warmly welcome those who seek our help and earnestly strive to improve their lives.
  • CONVENIENCE AND AVAILABILITY. Our Search-and-Schedule app allows clients to self-schedule first-time appointments 24/7 through the website, filter by categories important to them, schedule appointments when it’s convenient for them, and display only those providers actively accepting new patients.

Therapist Values

  • EMPOWERING PROVIDERS BY REMOVING SMALL BUSINESS BARRIERS. Westside’s model allows therapists to thrive in private practice by removing two of its biggest barriers: generating referrals and billing insurance. Therapists determine themselves when they are available to see new clients. We match and refer clients their way, and we do the insurance billing once sessions occur. The overwhelming feedback we receive is that therapists are relieved that we handle so many of the admin tasks, which grants them much more free time and the ability to focus more exclusively on mental health care.
  • ADVOCATING FOR WORK/LIFE BALANCE. Westside encourages team members, providers, and partners to do as much as they want but not more than they can. As a mental health company, we know the importance of preserving mental acuity. The benefits of avoiding burnout far exceed the benefits of doing too much for too long. By removing time-consuming administrative burdens, many of our providers are able to pursue other interests including research, writing, volunteering, music, culinary arts, travel, and additional time with their families.
  • OPPORTUNITIES TO EARN A GOOD LIVING. The providers who join our group have the ability to make a good living in private practice by maintaining a 20+-session-per-week caseload. We encourage therapists to pursue their life goals, and we try our best to help them do so.
