Strategies for implementing classes in Typescript

I've been working on incorporating more classes into my project, and I recently created an interface and class for a model:

export interface IIndexClient {
  id?: number;
  name?: string;
  user_id?: number;
  location_id?: number;
  mindbody_id?: number;
  appointment_type?: string;
  found?: boolean;
  time?: string;
  status?: string;
  submitted?: boolean;
  consult_status?: boolean;
  consultation_id?: number;
  consultation?: IConsultation;
}

export class IndexClient implements IIndexClient {
  public id?: number;
  public name?: string;
  public user_id?: number;
  public location_id?: number;
  public mindbody_id?: number;
  public appointment_type?: string;
  public found?: boolean;
  public time?: string;
  public status?: string;
  public submitted?: boolean;
  public consult_status?: boolean;
  public consultation_id?: number;
  public consultation?: IConsultation;

  constructor( data: Partial<IIndexClient>,
               private locationService ) {
    Object.assign(this, data);
  }

  getLocationName() : string {
    return this.locationService.locations.filter((loc) => loc.id == this.location_id)[0].name
  }

I want to use the getLocationName() function in my code, but it requires an instance of LocationService to access the locations. The problem is that every time I create an instance of IndexClient, I have to provide the LocationService:

this.client = new IndexClient(this.client, this.locationService);

Is there a way to access a provider's value inside my IndexClient class without having to provide it each time?
