Is losing 25lbs in 3 mnths a reasonable or achievable weight loss goal?

Yes: The answer depends on your baseline weight but in general a pace of 0.5-2 lbs/week is acceptable and achievable. The most important thing is how you are doing this. Make sure you stick to a program that you know you can maintain lifelong instead of falling for the fad diets/regimen. Good luck to you.

Usually: Recommended rate of weight loss is usually 1-2 lbs per week. So a 25 lb weight loss in 3 months is reasonable. Try not to think of it as going on a diet; rather, make changes in your eating habits that you'll be able to continue for the rest of your life. The hard part comes after you've met your goal and are trying to maintain it. Check out this site for tips: http://www.Nwcr.Ws/stories.Htm.
