10 Examples of A Thank You Letter to Mentor and Friend

Dear ____________,

I don’t even know where to start!

Thank you seems so insufficient for everything you’ve done for me. You’ve been a mentor, a friend, and a sounding board – I really can’t imagine what I would have done without you.

Thank you for always being there for me, no matter what time of day or night it is. Thank you for being a sounding board for my crazy ideas, and for always giving me honest feedback.

Thank you for being someone I can always count on, no matter what.

I am so grateful to have you in my life, and I hope that our friendship continues to grow in the years to come.

Thank you, from the bottom of my heart.

With love and gratitude,


P.S. I’ll buy you a coffee next time I see you!

Dear ____________,

Thank you so much for being such an amazing mentor and friend. You’ve helped me through some tough times, and I really can’t thank you enough.

Thank you for always being there for me, no matter what problems I was trying to overcome. Thank you for being someone I can always count on, it means the world to me.

I feel blessed to have met you. Thank you, and please do not ever hesitate to ask if there is anything I can do for you.

Warm wishes,


Dear ____________,

I wanted to send you a note to let you know how much I appreciate you always being there for me, both as a mentor and a friend.

I’ve lost count of the number of times you’ve helped me out, stuck up for me, and went out of our way for me.

You’ve always been there when I needed you, and I really can’t thank you enough.

Thank you for being an amazing mentor and friend, I really appreciate it.

Take care,


Dear ____________,

Thank you so much for being my mentor and such a good friend over the years.

Having someone like you in my life is literally what has made me the successful person I am today, and I owe a lot to you.

You’ve stuck up for me, believed in me, counted on me when I doubted myself, and honestly, without someone like you I know I would have lost my way.

I shall always be indebted and I can only hope that I make you proud in some way.

All the best,


Dear ____________,

I just wanted to drop you a letter to say – thank you for being an amazing mentor and friend!

Without your encouragement, advice, and support I wouldn’t be where I am today. For that, I shall always be grateful.

I won’t go into all the times, projects, and things you’ve helped me with, you know what those are.

Thank you for all that you have done. If you ever need help with anything, please never hesitate to call me.

Your friend always,


Dear ____________,

You have helped me more than you will ever know, and for that I shall always be grateful.

I wasn’t sure how to express that, so I thought I’d start by sending you a thank you letter!

It’s going to be impossible for me to forget the role you’ve had in my life; you have been a mentor, friend, and confidant.

I really hope there is some way I can repay you, but it’s going to be difficult with everything you’ve done!

God bless,


Dear ____________,

You have been a mentor and friend to me for years now, and I really wanted to take the time to tell you how much I appreciate all of your support.

I know it hasn’t always been easy, but I really do appreciate everything you’ve done for me!

Thank you for being there for me, and I hope that our friendship continues to grow in the years to come.

All the best,


Dear ____________,

You have been the most amazing mentor to me over the years and I’m proud to also call you a close friend.

Things couldn’t be going any better for me right now, both personally and professionally, and I owe a lot of my success to you.

I wanted to write this letter to let you know how much of a positive influence you’ve been on my life and how much it means to me.

I shall always be incredibly grateful for your support.

Kind regards,


Dear ____________,

I want to thank you for everything you’ve taught me professionally and personally.

Your wisdom, expertise, and continued support has had a huge impact on my professional and personal development, and I believe my current success is at least in part to your mentorship.

I’m also very proud to call you a friend, and know that you’re someone I can rely on, just as you can rely on me.

I truly appreciate everything I’ve learned from you. You shall forever remain a major contributing factor behind my success.

Kind regards,


Dear ____________,

I’m writing this letter as a token of appreciation and to let you know how grateful I am for all the support you’ve given me over the years.

Without a mentor as knowledgeable and generous with their time as you’ve been, I wouldn’t have been able to achieve the success I have.

You’ve always been available, provided sage advice when I needed it the most, and never made me feel like I was a burden or like I was asking silly questions.

I hope to one day be able to return the favor, but for now I’ll just say thank you from the bottom of my heart.

Yours truly,

Should You Send a Thank You Letter to Your Mentor?

If you have a mentor, chances are they’ve had a pretty big impact on your life – professionally and/or personally.

So, it makes sense that you would want to thank them for all their help, right?

But is a thank you letter really necessary?

Here are a few things to consider before sending a thank you letter to your mentor:

  • How close are you with your mentor? If you’re on good terms and have a close relationship, then a thank you letter would be a great way to show your appreciation.
  • What type of help has your mentor given you? If they’ve just given you some advice here and there, then a thank you letter might not be necessary. But if they’ve really gone above and beyond, such as helping you land a job or writing you a recommendation letter, then a thank you letter is definitely in order.
  • What’s your mentee/mentor relationship like? If you’re not sure if your mentor would appreciate a thank you letter, then it might be best to err on the side of caution and not send one. You don’t want to make them feel uncomfortable or like they have to respond.

If you decide to write a thank you letter to your mentor, here are a few tips:

  • Keep it short and sweet. You don’t need to write a novel – just a few sentences expressing your gratitude will suffice.
  • Focus on specific examples of how they’ve helped you. Mentors are more likely to be touched by stories of how they’ve made a difference in your life than by generalities.
  • Feel free to use any of the examples I provided above as a template. Be sure to personalize your note, and I’m sure your mentor appreciates it.

Remember, it’s the thought and the sentiment that counts. It’s more important that you send a thank you note than the exact wording!
