TM Diëtetiek

What TM Diëtetiek does

TM Diëtetiek is a sole-proprietorship dietetics and personal training practice based in the Netherlands, founded in 2017 and operated by registered dietitian and personal trainer Tessa Mossinkoff. The business delivers individualized nutritional counseling through three consultation tiers (intake at €120, follow-up at €48, short consult at €24), all of which are claimable through Dutch health insurance depending on the client's policy and deductible status. It complements dietetics with personal training services — one-on-one medical personal training, duotraining (two-person), and a weekly Women Only group class — offered at Optisport Health Club in Mijdrecht and online.

The practice targets four primary personas: individuals pursuing general lifestyle improvement, recreational to competitive athletes, pregnant women, and individuals with chronic conditions such as hypermobility syndrome (HMS), fibromyalgia, and rheumatological disorders. Tessa's personal lived experience with HMS and fibromyalgia, combined with formal credentials including Voeding & Diëtetiek (2018), NSCA personal training (2017), Post-HBO Sportdiëtetiek (2019), Zwangerschapsfitness (2022), and HBO Leefstijlcoach (2024), differentiates her positioning in these niches. Service is delivered at two physical locations (Mijdrecht and Bussum) plus online video, with published opening hours across four weekdays.

The business operates with no external funding, no proprietary technology beyond a standard WordPress content site, and a direct-to-consumer go-to-market reliant on personal reputation, word-of-mouth referrals, and an organic digital presence across Facebook and LinkedIn. Revenue is generated purely on a per-session basis across professional services streams, with no subscription, contract, or intermediary channel. There is no evidence of institutional investors, M&A activity, or plans for organizational scaling beyond the current solo-operator footprint.

1. Dietetics Consultations (Intake, Follow-up, Short Consult): Individual dietetics consultations including initial intake (€120), follow-up consultations (€48), and short consultations (€24). These are claimed through Dutch health insurance (zorgverzekeraar), meaning patients may have partial or full coverage depending on their policy and deductible status.
2. Personal Training Sessions: One-on-one (medisch) personal training and duo training (2 persons) services. Pricing is quote-based and requires contact for details. Training is offered at Optisport Health Club in Mijdrecht and online.
3. Group Training (Women Only): Weekly group training class for women only, held Thursday evenings (17:30-18:30) in Mijdrecht. This provides recurring revenue from a dedicated client base seeking community-based fitness.
